Internet petitions are pointless, if you are serious about this then make a real petition and get it signed by community members. I assure you the people in control won't care about a petition signed by random people on the internet, they will want to see real signatures from locals. From an outside perspective it sounds fairly unreasonable, are you really going to put in and stay under 5mph if they change the rules to allow PWC's? Are there no other lakes in your area at all? It sounds like they want it to be a fishing lake, and if that is the case it will most likely never be what you want.
