I'm planning to visit my best friend who is about to start a combat medic course as a part of NATO program at army base in Austin Texas. The plan is to meet him in Austin when he finishes the course (9th of June), and go on a 10-12 day round trip that would take us from Austin to Huston, New Orleans, Memphis, Dallas and back to Austin, where we take a plane back home. We are thinking of renting a car a, picking out camping gear (since we prefer camping to motels), and hitting the road with no pre-set daily plans.
Since nether of us have ever visited US, I'd really appreciate any and all advice 2 European near-middle age guys could use on the road and camping. Like; is there a real danger of rattlesnakes in Texas, outdoors laws regarding camp fires (one of the things we swore to make is a real Texan chili and grill our own T-bone steak...), any gear we should or should NOT have... things like that.
Thanks in advance!
