S.B.
hi. i live in sd and this is sad to say i don't have alot of experience with that area. one place i would suggest visiting is a place called reptile gardens, located in rapid city,if they are still open. i haven't been for a lonnnng time. i think they also have a zoo. another place would be mt.rushmore. i agree though if you go in august, specially during STURGIS you are not going to find a room and if you do the prices are going to be extremly high. i used to work for a call center making reservations for SUPER 8 and a room that would normally cost $60-$70 was priced way over $120.00 just for one night. any ways happy early anniversary and good luck.another place to go for ideas about things to do is www.travelsd.com
also wanted to mention that if you like MT.Rushmore and fire works come visit over the fourth of july. they put on a awesome firework display.
