I have some time off before I start a new job, and was thinking about going on a little road trip. I want to minimize costs and my time frame is anywhere between a week to probably about 3 weeks. I was an avid camper in the summers of my high school and college years but I don't have as much experience camping this early in the spring. I'm looking to camp most of my nights and getting a cheap motel room now and then, especially at the start when it's really cold out. About far south (either east or west) would you guys guess I would have to travel to be able to camp over night with it being insanely cold at night? I've stayed in cabins with only screens in temps. inthe upper 30s/low40s. I have a decent 2 person 3 season tent, and am looking to buy a nice sleeping bag for the trip. Just looking for some interesting camping spots at this time of the year that won't be too cold. Any suggestions would be greatly appreciated.
