...reservations or just wait til there? were going to yellowstone may 21-25. Where are good camp grounds with showers? Were camping in tents. Should we stay in yellowstone or somewhere around Yellowstone? honestly im a little nervous about stayin in yellowstone due to bears! Do we need to reserve a camp ground before we go? we were thinkin about just waiting til we get there so we can see what our options are and location wise decide where we wanna be...? is this a bad idea though?
