I grew up in the Big Horn Basin in Wyoming. I am familiar with where Unit 37 is, but I don't have a feel for how bad the access issues really are. It is listed as problem in the regs and also in the MRS. I want to take my 13 year old son up there in 2013, and would appreciate any help anyone could give me with filling in the details on the access issues. Would 118 or 120 be a better bet? Thanks in advance for any help anyone can give.
