I think I need an abandoned warehouse, some wood and a few dozen volunteers.
Ray’s Indoor MTB Park is located in Cleveland, Ohio. It was started by Ray Petro, who realised the dissolute lifestyle of his twenties was going to kill him and turned to mountain biking instead. It’s an 80,000 square foot space with manufactured trails and jumps that is open over the winter for riders to keep their skills honed whilst the weather is poor. The Biking Hub visited for one of its last weekends of the season and did a long write up that had me jealous.
