My buddy and I scouted the Trans Mass in his Subaru this afternoon. A lot of the roads were plowed at each end where the houses stop. I got a little overzealous trying to cross one of the berms.
The dirt patches were mainly slick ice with rain on top. No way I'd take a bike on most of them now. I did see one small dual sport out on the road on the way home though. I can't wait to break in my rebuilt 1150GS on this trail next spring.
