Scoundrel, I don't think I'd be up for a 4800 mile trip this year but some time in July or Aug there is a trail that loops from Darby MT counter clockwise almost to the Washington border through Idaho. It's about 800 miles and should be doable in 5 or 6 days. 7 would be great. As I'm still not home yet I'll have to get back to you on this one. I don't know if I will want to do this in one of the SXSs or on the Quads. Depends on the other half and how into this she is going to be. I'm still in the planning stage and might see if I can swing this on the end of the Jamboree in Idaho. Doesn't have to start in Darby. If you are intrested in looking at this trail it is posted on the Fabcraft Website
