Proof of ownership/canoe registration
Actually, in Silly-noise, the DNR uses the numbers of various types of registered boats to determine where the funding goes for boat ramps. Also, they recognize that not all ramps have to be concrete -- they've contributed heavily to all 7 canoe launches on the Des Plaines River and two lake sites, here in Lake County. Only one of them is concrete, and nothing bigger than trolling motors are allowed at that site. It's the best bang for my tax buck I'll ever see... Doing the math, I'm paying $14/year for my 7 boats, which gets me unlimited access to 8 canoe & kayak-only launches, and 1 where we see an occasional trolling motor, in my home county. Another canoe & kayak only launch is planned for an additional lake site; construction has begun. In the county just west of me, there are 5 or 6 such sites, and two more planned (funded). So you might want to find out exactly what WI does with the boat reg money... ya never know until you ask.
I'll agree that registering canoes & kayaks is kind of silly, but since it helps build non-motorized access sites, I'm okay with it. Oh, and you only have to put the 2" numbers on your canoe if you motorize it. Sailing canoes don't need them. Oh darn!
Note that this year the DNR has decided that, for people who live in states where canoe registration is not required, not only do the canoeists have to show proof of residence in that state, but they have to carry a copy of that state's law that shows the exemption for canoes. For WI at least, that text is available on line; I can dig it out again if someone needs.
Hey, the news can't all be good!
