The 500 is the name of the place in Stillwater. It has over 20+ miles of trails. $25 for a one year membership. I ride there the majority of the time. You'll have to come up for a ride with the Heartland Spodes soon.motorider200 said:I live in Muskogee and have ridden at camp gruber. It is a fun place to ride. I've also done some riding at a place in Stillwater (forgot the name) it was a blast. BTW I will be moving up there next fall for college.
