Hi, I took my 2 kids to the boardwalk go kart ride and they would not allow my son to ride due to his height even thou his head was able to touch and was a tad taller than the required height stand at the entrance. They said that his forehead needed to go over the height stand. My son was in tears as he could not go even thou they allowed him to ride a few days back. Why have a height stand if the height requirement is still dependant on another standard that is hard to quantify like your forehead need to touch the middle of the stand? Thanks Michael
