In the October issue's Best Of Cleveland package, we name Ray's Indoor Mountain Bike Park as the city's best artificial wilderness. (I'll add a link to the story once it's posted.) It's a 103,000-square-foot former warehouse remade as a half-mile cross-country bike course of rocks and wood.
If you'd like to see it for yourself, but you're not a mountain biker, this Cool Cleveland party (click here, scroll down) on Oct. 16 gives you a chance. If you are a biker, Ray's opens for the season on Oct. 18.
