I emailed H&H Bass Club and this was their reply:

We fished Kincaid on 4/5/09. No one was cited but most of our members with longer boats, including me, received warning tickets for having boats longer than 18.5'. I read the discussion from your link, but don't have a login on fishin.com to reply.

If a cop pulls you over for speeding and he issues a warning instead of a ticket, he is still enforcing the law.
