National forests and state parks have plenty of campgrounds available with good facilities, and there are many other private campsites around here too.
There are also rest areas every 30-40 miles where truckers stop, and some Walmarts and Lowe's allow sleeping overnight in their parking lots.
But take advantage of the miles and miles of beautiful national parks we have where you can sleep in the wild like a bear. Well... a bear in a campervan.
