Took my son to see Hozier last summer. It was both our first time at the rocks and it awesome. We drove down from Laramie, parking was fine, had to walk a bit but nothing to complain about, almost got in the bathroom line thinking it was the line to get into the venue (close call), I drank some...
We did, most of it anyway. The river was high and the road was flooded at Taylor Canyon, so we drove in and out from Schafer road. Stayed at Gooseberry and Candlestick.
My sheep picture sucks compared to yours.
