Went out to the park to check out the or area today. Its definately geared more toward the dirt bike/4 wheeler crowd. There are a bunch of hill climbs and descents but they are all dirt. They had a few mud holes to play in, which were mostly standing water. Overall pretty nice place. It's free of charge and there are restrooms and water nearby. Riverside state park is located just above Spokane, wa. And here's a couple photos taken today.
