If you look closely, you'll see that snow is piled up nearly five feet deep outside in the parking lot, while the riders are wearing t-shirts. Ray's Indoor MTB Park
in Milwaukee, Wisconsin, has plenty of challenging things to ride, but you can also do laps on the fun cross-country loop. There's a reason why Ray's MTB parks in Cleveland and Milwaukee are popular. You can ride them all winter long, working on your skills and fitness, and never get bored.
