How do you travel if for a limited budget?

It can be quite an adventure to travel on the cheap. Most Walmarts let people park overnight, usually in the back with truckers. Most Walmarts have a snack bar, deli section, or restaurant and of course there are restrooms. We have spent the nigh in convenience store parking lots, also, always getting permission from the night manager. You can stop at stores and buy snacks like fruit, soda, pop tarts etc. to save money eating on the road.
