For anyone that's interested. Here is a story about the local bike park Andy and my Grandsons volunteer at frequently.
The park has been spearheaded by a local family in honor of their son who lost his life defending ours overseas. This is a world class park which will probably be hosting some huge events in the next few years. I've walked some of their trails, many I could not begin to walk on but would have loved to ride off-road motorcycles on back in the day. They're putting in narrow, floating bridges in some areas I think. There are bicycle teeter-toters, crazy steep hills and steep banked berms on fast corners.
