Hard to imagine living in Costa Rica without walls, they have many creepy-crawlies, big and small.
Camping has long been my periodic lesson in living simply, for up to a week at a time. It is an instructive way to vacation.
I don't know many people who later in their life wish they had more stuff. If I had life to do over, I'd have less stuff.
Except knives, firesteels and campstoves. Can't have enough of those....
