Welcome back to the new NEFF. Take a break from Twitter and Facebook. You don't go to Dicks for your fly fishing gear, you go to your local fly fishing store. Enjoy!
I use a float tube in the lakes around here with no problems (except for the high stumps, getting goosed by them really raises the heart rate for a second).
The regulations state:
What to Register
Any boat longer than 12 feet and all motor-powered vessels, regardless of length.
What Not to Register
Non-motorized inflatable devices.
Non-motorized surfboards.
Non-motorized dinghies.
Non-motorized racing shells.
Non-motorized canoes and kayaks.
in PA we do not have to register them but we have to get a "launch permit" to use the Pa fish commision launches. Maybe they should impse a "sanitary permit" to use the porta johns.
