Yeah, I have been hearing this rumor out at Bartlett also. There is nothing in the Arizona Statues that specifically outlaws wakesurfing.
Boating laws are defined under Title 5 Chapter 3 available at the following link: http://www.azleg.state.az.us/ArizonaRevisedStatutes.asp?Title=5
If anyone has gotten said ticket, please let us know the specific offense such as 5-341, 5-346, or whatever so that we may politely inform the officials that their duty is to enforce the laws not to make up legislation on their own.
That said, you may want to hold off on stalling out the board on the swimstep in front of them.
