We are the Brookings bikers and we have been constantly kicked out of the skatepark and left with no place to ride. All we would like is a fair treatment and be allowed into the park. The most common misconception is that BMX bikes physically damage the skatepark structures. Bikes ride on rubber tires, unlike skateboards and rollerblades, which use urethane wheels. Occasionally a rider, just like a skateboarder or rollerblader, will perform a stall or grind.
