ya, i believe the sheriff's are the same way...my friends and i were out jetskiing for the day and the sheriff's were out there launching at the same time. we wernt close to the shore, but too close for them, they came by and told us to move it out more toards the middle of the river, which was no prob, except for one of the guys with us, who started messing around too close again and they came back and gave him a ticket, a very expensive ticket too, but he couldnt say anything since they were cool the first time, and even when writing the ticket, the sheriff was still coool saying sorry but he did warn us and they are just thinking about the little kids who are playing near shore...hard to argue with that, plus most of the time they just hang around making sure no one does anything real stupid, i cant complain (then again i didnt get the ticket)
