We are driving from Bloomington, Indiana on May 31 to Yellowstone. According to a mapping website, the drive is going to take 25 hours. We plan on driving it in one haul, with a few hour nap sometime during the night. We are pulling our camper, so where ever we stop to nap, we will sleep in the camper. Does anybody have any ideas of safe places to pull over to sleep???? I heard that rest areas are patroled by cops, and if they notice you there for more than a few hours, they may run you off! Walmart?? A truck stop??
