Highbinder posted the stop locations a few weeks ago...
http://www.valkyrieforum.com/bbs/index.php/topic,3790.msg26118.html#msg26118The last gas stop, according to that post will be on I-81 at Exit 307 (in Virginia) at a Sheetz, right around 5:30 PM... about 100 miles out of Chambersburg. There was more recent talk that the northbound group was also going to stop at the Pennsylvania Welcome Center on I-81 to re-group, but that wasn't confirmed.
