First, slow board.
Second ... are you even looking?
30-45 minutes is going to be pretty tough. Widen that to an hour and that puts you 10k feet innamountains, 6-7k ft innawoods, or 5k-ish onnaplains.
Looking for dispersed camping with a fire pit, something you can get a vehicle to (4x4? Trailer? Compact/sedan? Offroad?), or something more established with water/facilities available?
Because for fucks sake man, you're literally surrounded by opportunities.
