I arrived at 8 pm & filled in the $ info & put the envelope in the slot. I picked out campsite #29 - randomly - there were many campsites available. I drove around for 15 minutes looking for #29 & finally, out of road fatigue, went back to the entrance & grabbed the card for #27 because I knew where that was! Getting back onto route 70 was really difficult. Some guidance at the campground would be helpful. Also - “wifi” doesn’t mean internet service. I didn’t have access to the internet at all. Not even google maps!
