Man, that sucks. I didn't know about his past. He helped me out a fair bit several times with my Alltrac, but then also ended up keeping all the money he owed me, so, I won't say it cancels out, but it's very strange. Oh, well. Good to know about in the future in case I run across him or anything he's done. He randomly showed up to an autocross at Packwood last year. I wish you the best of luck in tracking him down.
The last address I had for him was:
1010 NE 157th Ave
Vancouver, WA 98684
He was there last I talked to him in early 2006, but I don't know if he's moved.
