What's really worth paying to see in Rapid City, SD?

Definitely Deadwood...take a walk downtown and visit some neat shops and the bar where Wild Bill Hickok was shot...and the cemetery where he and Annie Oakley are buried. Also Kevin Costner owns a bar/casino downtown.

And as another poster suggested--definitely Bear Country--my husband and I loved it (as did our little dog--she got a doggie treat at the entry gate and loved looking out the truck window at the bears and wolves, etc) After the drive-thru, you can visit a small zoo with just baby animals.
