Review

"Alternate Routes has some of the toughest Ninja Warrior Obstacles around. They have the most accurate cliff hanger on the east coast and some of the toughest grip obstacles. They also host regular competitions where you can find ANW vets like Captain NBC, the Weatherman and many more. If your in the Baltimore area and looking for a challenge Alternate Routes is for you."-Chris Wilczewski
