The OP of this thread asked specifically about the merits of the north vs. south routes into Sand Wash. It evolved into a discussion about airplane shuttles.
I can say I agree with all the favorable comments about them being a very special treat as well as an economical shuttle option. Ya the midnight drive sucks, but that effort is always well worth the reward. The flights from Hite to Mineral Bottom and Green River to Sand Wash are a once in a lifetime opportunity. Now that my kids are old enough to drive, I'll send them on shuttle and let them enjoy a fucking cool airplane ride.
All that said, it has been over a decade of gas development since I've been to Deso, can anyone provide current info on the two driving routes into Sand Wash?
