Just got back from a great weekend at Coastermania. Wish I had read up about how Mantis messes with peoples legs. I rode it twice on Friday night and thought the ride was nice an intense. Afterwards I had muscle cramps in my legs and walked around with a limp for the rest of the weekend. I thought I was really out of shape or something. I did 8 days of Florida parks straight just a few months ago with no problems, so I thought it was weird having leg pains after just walking around Cedar Point for a couple of hours.
Now I know, beware of Mantis. Fun ride, but may cause pain.
