I was helping a friend strip parts off his mini-truck that he'd rolled in a drunken excursion after a wedding in Yosemite National Park. He went to great trouble to yank off the TLCA and his club stickers, he didn't want these two groups to be associated with some bozo who would get drunk, then total his vehicle in a national park. I was there at the same wedding, had taken his keys away (but he kept an extra in his wallet) and I had the only pickem-up truck that could haul the three parts that weren't toasted from the accident. He'd missed a turn at warp speed, hit granite, drove the passenger side tire into the passenger-side footwell, flipped over. It partially collapsed his interior cage. Ruined all four rims, Xfer, transfer, both axles, etc. and so on. I know we took the rear custom bumper, one 90wt soaked sheepskin seatcover, and probably his tool box and contents. I think he even broke the engine block.
I ended up buying my 'Cruiser from him in Jan 1989, so it has to be 1988 or earlier that I heard about TLCA. I joined sometime after that, thus the #1559 member number. And for what it's worth, I joined for the advertisers (that was before I had interweb access) and for the tech articles. Either one of those two alone has made membership worthwhile.
