I'll be leading 7 Mile Sat. We ran it recently on the pre-run. When we go to Uranium Arch there is a place I dragged my trailer hitch pretty good. We also have a few up/down steps. Mostly there are not a lot of obstacles. Let me think about this some more and maybe some Taco folks will chime in. Its a fun run so hopefully it still works for you.
Totally stock you say?
