Well, I finally bought a tow dolly...

I've been thinking about getting serious about car scrapping, but really couldn't afford a tow truck, and the costs would not be justified by my results so far. Ditto a trailer...at about two grand, a hefty expense after our slow season.
My compromise was an old beater tow dolly. 400 bucks out the door. Needs new straps which I found at Harbor Freight and I'll shoot it with some rust-oleum as soon as I have a decent day. It ought to be completely paid for with the three cars I'm scrapping over the next couple of days.
