I have tried to sell Mr. Onalark on ultralight camping (we go a fair bit), but the man just loves his toys too much. And that's why I keep buying cars big enough to haul all our air mattresses, tents, camp stoves, axes, firewood, and etc. up the mountains.
Every now and then I get a tiny victory and convince him to leave a camp stove behind.
But then he just buys an extra bundle of wood. -_-
At least he likes camping!
