I have one other local friend on a DRZ that's pretty certain he will join me on the venture, myself, and one other KLR who posted up on ADVrider from Springville NY (30 min south of me in Buffalo), but I do not know him personally nor is he committed.
Short answer, just myself on an S10, and someone I know personally on a DRZ confirmed. I'll lend him my DRZ's IMS Tank for the trip so he'll be at ~175 mile range and packing a Rotopax so we're not walking.
Plan is to meet up with my local friend early and slab it down the 219 to meet you around the PA line wherever you are, and from there, I don't care where, how far, how fast, how slow or how long we ride between then and Sunday.... If it's pouring rain, I'm all for slabbing it down the 219-220 to Romney depending on our spirits.
As far as the route, I'll have a Garmin 478 next week, and it'll be mounted up shortly thereafter, so I'll be able to use the file it once that's running.
