Enjoy. We like Jackson, it is a lovely beautiful town. We stayed at the Virginian RV park on both trips, it is a small gravel full hookup lot at the rear of a small, nice hotel, right in the heart of Jackson. It is all about location. Yellowstone is wonderful. Plan on at least 4 days of touring, at very least. We have stayed at both Grizzle RV and KOA West Yellowstone. Grizzle is right at the park entrance, well groomed, but with few amenities. KOA is a great KOA, large sites, heated pool, gym, small restaurant, and the preferred sites have concrete tables and benches and an adult swing bench. Really, just nice. Its been a long time since we were at the Black Hills, but it has great memories.
