"In 2004, we opened up Thanksgiving weekend. We were open through the winter. We did OK, but I wasn't sure I wanted to do it again. It was a lot of work.
"I got a phone call from Subaru Great Lakes Region -- from a person named Aspen. She said, 'We bumped into your Web site on the Internet, and we think it's really cool. We'd like to send somebody out to see it. And we might want to get involved.'
"We swept up the place, and I gave them a tour. We were able to strike a deal within the next few weeks."
"That was the bridge that got us to the next season."
"Subaru has really gotten involved. It has sent checks and cars. We've done showings at the park, and we've had events. Subaru has brought in pro riders, and we've had gimongous parties there."
"I was able to parlay that into a relationship with Gary Fisher® bicycles. They sent somebody over, and they've been involved since summer of 2005. It's a natural group of partners."
"The park is set up like a giant Monopoly board inside of an old factory. It's split up into sections, from beginner to expert. We try to build everything to be as safe as possible.
"It's not like a mountain bike ride in the sense that you head to a state park and go out in the woods for two hours. It's very social. It's like a big party. We've got these big lounges. There's no drinking – everybody's just high on riding their bikes and trying different things.
"We've designed it so you can bring a group of riders that you normally would not ride with – like a pro, and your girlfriend, and kids – and there's something for everybody to do. You wouldn't take that whole group to the state park and ride because somebody wouldn't be in good-enough shape or something. You've got a wide range of experience.
"Plus you can plan a trip next year and not worry about the weather – you just have to get here.
"I couldn't make it on just my local riders. We started to get folks who would travel. We needed to make it a weekend's worth of fun. So every chance I had to expand, I did. And I've expanded the park every year since we've opened. We now have 120,000 to 125,000 square feet.
"Subaru considers me a national attraction, and all my other sponsors do, too. We'll see 300 to 400 to 500 people on a weekend."
"We used to only let in BMXers on certain days. But now that the space is larger and we've made a bunch of improvements, we're letting in all bike riders – whether they're on a BMX or a mountain bike. They ride in different areas in the building."
Ray's reopened in the middle of October 2009, and the park has numerous special events planned throughout the winter. To see more photographs and to find out more about the park and its events, visit www.raysmtb.com.
Ray's MTB Indoor Park started as a dream that took eight years to become a reality. "It's the world's first indoor mountain bike park," Petro mused. "They've had indoor skateboard parks, and they would let people ride their BMX bikes in there, but I was like, 'You know, if you had enough space …'"
