Going camping this summer with some friends, need some good country songs to listen to, any ideas?

I'll be going camping this summer with some friends from school as our senior week cuz its what we could all agree on. except we need songs for the trip. we'll be in the car for about 4 hours round trip. any ideas? i really like the 90s and shania twain, but she's already on the list. i know there's a lot of good songs i just can't think of any at the moment
