There's an ecology off the 76, and then most the other good yards are in the Otay mesa area. 805 South, exit main street turn left, goto Nirvana, turn left, at T at the top of the hill turn left or right. Right is Ecology with the domestic yard being on the north side of the street and the imports on the right. At the end of the street is PAP, which hardly has anything Cherokee, but when they do, it has some decent parts. If you skip turning on Nirvana and follow main, it will go up towards brown field and there are a ton of yards in there.
