I've always wondered why, if law enforcement were truly interested in apprehending drunk drivers, why they didn't set up checkpoints in bar parking lots. Perhaps because that is NOT their main concern, (at least not in California) where a couple of DUIs are issued but many, many cars are impounded for such things as lack of insurance or failure to present proper ID. It's all about impound fees and car sales here.

It would be bad for business. And it might solve the problem, which is not on their agenda.
A lot of RI $$ is based on tourism. Newport RI is known as a drinking town with a sailing problem. :)
