Heidi and Mike have a universe all their own and a blog called Vandwellers and another, Vantramps for folks who live in vans like her and Mike. She's also a bit of a homesteader, as much as one can be living in a van. From what she showed us there's a lot you can do. For instance she's making rice and a whole lot more in a thermos. Apparently there's a little community of thermos cookers. It was a fun coincidence and exchange. Happy travels Heidi and Mike.
