I was at Tie Flume a couple years ago, very nice.
I grew up in Sheridan and spent many a night in the Bighorns.
They have drinking water available, but is hand pumped.
If you need to fill up, Bear Lodge (at the intersection of 14 and 14A) should have water available as well as fuel.
The climb up through Shell canyon (hw14) is gorgeous as well as Shell Falls and they have RV parking there as well.
Dead Swede CG is nice as well.
I'll try to post up a couple Pics in a bit.
