I had reserved site 54 through recreation.gov but at the time I thought it odd the site would not let me put in my rig size.  So I just went with it.  Mistake.  My 30 footer wouldn't begin to fit since the pull off the road is shared between 54 and 55.  I've never seen a CG where a pull through is split into 2-3 'sites'.  So I drove around the park (which was mostly empty) and in spite of the giant signs screaming RESERVATIONS REQUIRED MAY 1-SEPT 30, I parked in very large site 71 which had midday sun for my solar and some shade in the late afternoon.  Did the kiosk sign in thing and no one has bothered to check me out.  The signage here is ridiculous, even in the bathrooms - lists of fines for everything!  I guess they've had to put up with stupid, rude and inconsiderate people.  Sad.  No dump station (there's one at park HQ down the road south) but there are several water hydrants through the park.  Mosquitoes were quite annoying along with a plethora of nonbiting flying critters my dogs enjoyed hunting.  The Wind River runs along the park with a railroad on the other side.  The 2x trains a day were NOT that loud and were gone in about 3 minutes.  Road noise from the highway is moderate but most city folk won't notice it.  Fishing isn't much fun because the river bank is steep with only 3-4 sets of stairs to the water.  The birds, however, are numerous and very happy to be here.  Had a momma turkey and 8 fledglings walk up to and under my trailer!   I would stay here again but at a cooler time of year.  The frequent breezes ameliorated the heat to a survivable level.  No T Mobile here at all.
