It sounds simple enough...
Right up until we started planning for it.
Before I get into that, I should go back to the start...
Of leaves and trails
Years ago, I lived in the Washington, DC area for about a year. While living there, I had bike commuted to work many times on the W&OD Trail, a very nice, if often crowded, converted rail trail.
Terry was intrigued about riding the rail trails back East, and wanted to see the fall colors back there sometime as well, so we decided to combine the two desires and ride the trails during leaf season.
In researching our options, I found a couple of very helpful websites, for Bike Washington and the Allegheny Trail Alliance, on which were described two major trail systems: The first, down the Chesapeake and Ohio Canal Towpath, a canal towpath converted into a bike/hike trail (from Washington to Cumberland, MD), and the second, down the series of converted rail-trails dubbed The Great Allegheny Passage (from Pittsburgh to Cumberland).
