To update this thread, I did end up staying three days at the NFS Bear Lodge cg. The
cg was re-opened just a few days before my arrival. This is in the Wyoming part of the Black Hills NF. It is a nice little cg with easy access from the hiway with only 7 sites. Of these only about 4 are suitable for big rigs. It has a vault toilet and each roomy site has a firepit and picnic table, $10 per night. It was always less than 50% occupied while I was there. It provided me and my Ryker good access to Devils Tower. The only negative here was the hiway noise, especially this time of year with hordes of motorcyclists roaring up the hill towards Sturgis.
