This is an annual trip to a Bible camp, generally we fly and rent a car. We have been fortunate enough to tour Yellow Stone and Green Gorge by car. This summer a friend is renting us his RV!! As a former homeschool mom (wish I still was) I want to cram in as much as we can. I have yet to go to Mt. Rushmore so I truly want to hit that on this trip. I think our sightseeing will actually go from Lander, WY back to Little Rock, AR as there will be little time on the way to camp. We plan on going through Thermopolis to swim at the Screaming Mimmie, and are looking for fun (cheap) outings for the boys. They are ages 4-16. Can't wait to hear from all you seasoned travelers!!!! Thanks in advance!!
