I feel your pain, (in the ass)! You need to get your local ELECTED officals involved as they are the ONLY officals you can hold accountable, (With your vote!). Alot of the Regional Planning boards or State waterway/Wildlife commissions are APPOINTED positions, so they are immune from the wrath of the general public! Try contacting NMMA or BoatUS, they SUPPPOSEDLY have lobbists in DC, BUT so far, neither has done much to help us powerboaters here in FL.
We've started a couple of grassroots boaters/H2O water front property owners groups to FIGHT this B/S. Here are their websites;
Check out these websites and you see how we generally approach these issues from all sides.
Call me (407)-306-3636 work Ph.#, if you want, and I'll give you all the help I can. Hang in there, there is strength in numbers, and we are definitely getting bigger and louder!!
PS Alot of the eco-radical groups feel that we DON'T have the right to boat in the state/national waterways!
