Capitol Reef National Park
There are 127 out of 400+ national parks that have entrance fees, but on these freebie days, you can roll right through those fee stations, after you observe the law and stop at the stop sign, of course--unless you want a map. You should probably stop and get a map, and say hello to the friendly people behind those sliding windows and doors.
