I remember a few years back when I first met pb84 and he graciously took me on a tour of the Los Angeles basin. During the flight, we had a discussion about possible forced landing sites. The freeways were impossible, being far to busy. I decided the railroad tracks would be probably be OK. pb84 opted for the concrete ditch which is the Los Angeles River. That would be OK, as long as you don't meet the Terminator on a Harley!
