We took Grayson to Kings Island on Mother's Day to see if the new Camp Snoopy area was open. We found out that Grayson was 40 inches tall after I had him measured and then we rode the Woodstock Express which he was just tall enough for. This ride used to be called the "Beastie" when Shelia and I were kids and it was my first roller coaster. Back then, Planet Snoopy was called "Hannah Barbara Land" and there were no restraints on the roller coasters.
