Walnut Meadow is okay for ONLY an overnight. Restrooms and everything else needs much repair. Didn't find the office open. Lady in golf cart came and asked two questions. How long? and do you have PA or GS? Took the fee cash only and took us to a site, At least they were mowing the grass.

I travel that route frequently when we rv and I usually pull off at one the popular truck stops so family can nap for a while and there is always fuel, nice place to eat and well lit for safety. Then we sometimes stay at the Wal-Marts you can see from the interstate. Lot cheaper than rv parks.
