I rode Pgh-DC last summer with my 3 kids age 13 -23. Started in McKeesport/Boston PA as the road to Pgh wasn't finished and although I did a scouting trip one Saturday, it wasn't pleasant and safe to take the kids on a fast road from the City of Pgh to McKeesport. We had a blast. You do need a bike with fatter tires and my 13 yr. old had shocks and had the most fun aiming for things I avoided. Fenders are important, too as it gets muddy when it rains.

We did about 60 miles/day over 6 days and stayed in guest houses and a rustic b&b, spending about $40/person per night for lodging. The best guide book to use with all the amenities available throughout the trail (growing no. of bike shops, places to stay, restaurants, etc.) is called TrailBook 2008-2009. It was $10 bucks locally but youcan order it from Fieldstone Press, 522 Handwerk Rd., Markleton, PA 15551 or through the Allegheny Trail Alliance website: 222.atatrail.org.
