How do you get around mill dams? anyone put wheels on their boats?

I did. On Montana's Madison way down low at Cobblestone it was a hundred yard drag to get out. When I was a kid my dad made a cart for my canoe. So I made a similar cart for my boat. It worked. The cart was still a grunt, but far more easier than just dragging. I called it my Cobblestone Cart.

Cobblestone has since been closed because of New Zealand mud snails.

Snails! They always have an excuse to close something.

I did cut two slot holes either side of the cart, so my trailer winch strap could hold the cart tightly to the bottom of the boast.
