I've often thought about doing as your wife suggests: selling everything and just living out of a camper. I'd love to just drive around Japan, camping and taking photos. My wife would never go for that idea. And, as you say, it is nice to have a homebase.
One of these days I need to get over there to go fishing with @enginewitty too. Actually I haven't been fishing in years, since before moving to Japan, so I'm sure I'll do a terrible job, but will be fun just meeting and chatting. When I make that trip, you should drive down too. I believe @coinjoe already volunteered to meet up with us as well. He's in southern Indiana.
