Bring your paddle and a life jacket, we'll supply the canoes. The Beaver is one of the best paddles in southern Ontario, and it runs across the road from the event. Paddle down to Free Spirit Tours in Heathcote, leave the canoe there, and we'll arrange for its transport back later.
You'll just have to have a car parked down there so you can drive back. The float is a beautiful, gentle, wild 6 hours, so you should be on the water for no later than 9am if you want to pull this off before things get serious back at the tent. Pack a camera, expect to see wildlife.
