My daily ride is on the Montour trail 0-17and I have ridden different bits to about the 30 mile marker. Most of it is crushed limestone but a few places it's a little rough <http://maps.google.com/?ie=UTF8&ll=40.302718,-80.145028&spn=0.007282,0.013733&t=h&z=16&layer=c&cbll=40.299067,-80.145849&panoid=_r5qw5NZQOth6jp2jqK-PA&cbp=1,316.99317021741973,,0,9.217433922226252> If this link works this s one of the roughest places where there is a road crossing. Search for "the historian" he rode it this summer all the way to dc
