But that because the Trails do go from place to place. I had a sister who once moved to Detroit to work for GM. She was on the GM test track and they showed her how to avoid an accident using the berms and side of the roads (i.e. you see a car coming to you, how to get out of its way using the berm and sides of the road). She told them that was good, but she was from Western Pennsylvania and the berm rarely are more than 6 inches and on the side of the roads you have either a hillside or a cliff-side (People In Western Pennsylvania tend to call any steep incline along the road going above them as a "hillside" and any steep incline along the road as a "Cliff-side". More convention than law.). Thus she told them in Western PA you only have one choice, leave the other car hit you. Given these narrow roads people liked the Rails to Trails.
Another factor in Western Pennsylvania has a lot of left over old rail beds from Coal mining days. The mines are now mined out but the right of ways still exists. The best example of this in the Montour Trail in the South Hills of Pittsburgh. In the 1790s the single richest mineral deposit ever found was found in what is now Mt Washington section of the City of Pittsburgh. The mineral was the "Pittsburgh Seam" of coal the reached from Downtown Pittsburgh to Green County. This started to be mined soon afterward. This coal was found to be good for Steel making and th primary reason Pittsburgh became the Steel capital of the World in the late 1800s (This coal is still mined for steel making, but today shipped overseas more than use domestically, in fact Western Pennsylvania imports coal from the West to generate Electricity while coal from the Pittsburgh Seam is shipped overseas, gives you an idea how valuable the coal is for steel making).
Anyway, the Pittsburgh Seam started to be mined in the 1790s, increased in the early 1800s and by the early 1900s was being mined around the border of Allegheny County (Pittsburgh is the County seal of Allegheny County) and Washington County (The county between Allegheny and Greene County). To get to these mines the Montour Railroad was built (First in the 1880s and then rebuilt to haul heavier loads in the 1920s). The mines started to close down before WWII but enough mines kept open to keep the Montour Railroad in business till the early 1980s when it closed down (It was kept open by several side tracks into Washington County that kept the railroad in business long after the mines along the main line had closed down). Anyway the last owner of the Montour Railroad liked rails to trails when he first read about it and helped form the Montour Rails to Trails council to convert the old Railroad to a Trail. He was able to do so for when the railroad was built the Railroad did NOT just buy a right of way through someone's property but instead purchased the land the railroad (and now Trail) is on outright (i.e. The Montour trail do NOT own a Right of Way, they OWN the land the Trail is on). Now unlike a lot of other Rails to Trails, the Montour Trail goes right through the suburbs built up since WWII. The Suburbs had NOT followed the railroad which went on a semicircle through but around the City of Pittsburgh but along roads built to connect the Suburbs to Pittsburgh. Thus the trial in convenient, easy to get to and a quick trip off the trail to various section of the South Hills. Now the South Hills Roads tend to be narrow but passable so the Trail is both used to connect people and leave people travel a good distance.
Now, another coal line that has been converted to a rails to Trail is the old Chesapeake and Ohio Line which is now the "Great Allegheny Passage". At the present time you can go from McKeesport Pa (an old city on Allegheny county) to Myersdale Pa (An old Borough in Somerset County) a distance of 102 miles (and from McKeesport connect to the Montour Trail). Whenever the Trail to the Mt Savage Tunnel is finished (Scheduled for "late 2005" and it is late 2005 but not yet open to my information) you be able to go to DC from McKeesport on the Trail or a distance of 318 miles (And if you use River road along the Monongahela River get to Pittsburgh from McKeesport on a fairly level road).
The route is a lot flatter than any other route through the Appalachians:
Furthermore you can use the Panhandle trail (another abandoned Railroad) to get to Weirton West Virginia via the Montour trail:
http://www.panhandletrail.org/Welcome.htmPlease notes parts of the Montour and Panhandle trails are NOT finished yet, these need new bridges and tunnel rehabilitation scheduled within the next one to two years.
Closer to my home town of Johnstown, the Ghost Town Trail, Hoodlebug Trail and the West Penn Trail are joining up to bypass US 22 as a major road connecting the County Seats of Blair County (Hollidaysburg), Cambria County (Ebensburg) and Indiana Counties (Borough of Indiana). These Trails are NOT as old as the Great Allegheny Passage but future plans include expansion to Greensburg (County Seat of Westmoreland County) and connection with the Great Allegheny Passage and thus Pittsburgh and indirectly Washington DC.
My point here is do to the topography and history of Mining of Western Pa you have a lot of Rails to Trail projects and they are popular given the state of the roads and the topography of the roads. In flatter areas I see less needs for Rails to Trails, but in my area they are a huge plus.
