Hi there,
Pretty much same old same old for me. Relatively boring job that's way too far from home and then much child wrangling.
Black Walnuts, bleh, don't like nuts. How many trees do you have though? That wood is worth a LOT becuase it is so prized by woodworkers. I've heard of people planting a grove of those trees as their retirement fund.
PM me your e-mail and I'll get it to DiC, I'm in contact with him on a couple of other forums.
On the missions thing for your kid, Thiland is generally a lot safer than we have the perception of, even in the extreme north near Burma, or Myanmar or whatever it's called this week. Our church has sent a missions team over there for the last two years and they've had no problems at all. Of course they are working with an established orphanage that's run by our denomination(Foursquare) so all of the cultural considerations are well covered. I wouldn't suggest that he go alone but maybe look into contacting Foursquare International (Foursquare missions arm) and see if they would use someone. They have a large presence in Thailand.
