This will be our first trip. Heading to Custer State Park next week. It will be Grandma and Grandpa (early 60's), myself, husband, and 3 kids ages 11, 9, and 5 1/2.
Looking for advice or opinions on which cave to tour - Jewel or Wind. Is there much of a difference? Should I make a reservation? We'll be there 8/15 - 8/19. Thanks!
