My mother in law lives in Lodi, so I've flown into there once or twice to pick her up to take her on a flight. The airport runway is pretty rough, and the communication in the air is pretty bad. One time, I stated I was going to do a standard tear drop entry, and got told off and told to avoid overflight. Not so bad that I wouldn't go back, but if you're flying around that airport, definitely keep your head about you and watch for NORDO traffic.
I've heard some folks say it's one of those privately owned airports that is "public use" in name, but in reality they'd prefer if you treated it like a private airport and mostly stayed away. I dunno about that myself, but I could see it being the case.
