I'd say California laws are the worst to deal with, the beauty of Ca laws though is enforcement. Nobody wants to enforce the laws on the books except for vendetta reasons. With the amount of law written most overly modded vehicles would be illegal in Ca, from lifted 4x4's to lowriders. There is so much bs on the books you'd be startled if you actually knew what is and is not legal. Just for starters everthing must be C.A.R.B. approved or it is illegal, and you must have the sticker attached to the vehicle or even if it is legal it is still illegal. I think it is safe to say that most anyone on this board that has anything over 33" tires could be sited for your headlights being to high along with the frame. Lowriders play the other end of that scale. Komifornia is by far the leader in making it hard to do anything to a vehicle. Sure other states have things that make you go nuts but out of several states I've lived in Wisconsin, North Carolina, Arizona and California, California is the worst. Of course since I am from CA I may be more aware of the bs involved there since that's what I used to do.
CA is probably the worst for wheeling too even though we have the most areas to do it in, it also is probably the most radical demo/liberal in the country. Plus they probably have the most nature nazis' to boot.
