We are going to be traveling through Rapid City area on our way home from Yellowstone and thought about tent camping around Mt. Rushmore. Is there any special events going on during this time period like fireworks or activities? What days? Is it crazy crowded? Could we pull in and get a tent site with electric if possible without a reservation? Would we be able to see same activitities on the 2nd or 3rd of July instead of just the 4th?
