The Ms150 in NE Ohio aka "Pedal to the point" (cedar point amusement park) is a great ride. I rode in 92-95. There was aprox. 2500 people riding when I was, and I've heard it has grown. The last couple of years we camped at a campground a couple miles from the park and usually had free or discounted tickets to get in to CP. After riding 75+ miles a roller coaster can do wonders for the tired muscles.
If your wondering if you can do it, you can. Rest stops every 10-12 miles fully stocked. My dad even rode with me. (First year he was 45+ and about 50+ pounds over weight, riding a 10 year old department store bike.)
The route is pretty flat, unless they still have the lunch stop in the vermillian (sp?) river valley!! Nothing like a steep 15+% climb right after lunch.
I plan on riding in this/next (2003) year as I will be moving back to the area in January.
Any other Questions?
