I hate drinking and driving. Been biking to and from bars for years-- way, way better than having everyone argue over splitting a cab. Or rolling the dice and climbing behind the wheels themselves.

However, I think the law should allow an officer to stop a person obviously too drunk to operate a bike. Drunk cycling isn't exactly an optimal solution.

It's the kind of situation that benefits from ambiguousity: By enforcing selectively, the cops can keep people from hurting themselves while allowing marginally intoxicated folks to get home safe.
