It usually starts on the main road at the hitching/unhitching strip on the right side facing the marina. It goes all the way down to the marina and that is where they give out the prizes. We were in it two years ago, but last year decided to sit on the side and enjoy the whole parade. The staff did make a couple of carts and all the carts were great. Last year the staff at the bike barn asked my kids to take pictures for them with disposable cameras and if they brought the cameras back to the barn, they would get a prize. They took pictures of all the carts and they received free rides on the mouse boats.!
The time it starts is usually 10 am. There is also a guy that walks the parade while playing the bagpipes. The best thing is he practices for a couple of days and he is so cool!
