OT: Huron River Tubing

So, this is way OT, but the Mgoboard has become one of my most trusted sources of AA-related information. Anyways, I was just wondering if any of you have tubed/canoed the Huron River, and if so, if you knew any good sites for launch and landing? I'm looking to lead a tubing trip next weekend, but I don't know any sites. Much appreciated.
