I have been out of town, I'll try to take care of these trees soon.

I rode the trail this afternoon and, to my surprise, saw the jump that dc-Mtnbiker is describing .  This jump was built by some unknown person that is not authorized to make changes or additions to the trail (like it was in their back yard.)  The jump is on both sides of a "sometimes wet and sometimes dry" water overflow creek. These jumps are fun but should not be installed where they can wash away. As most Trailblazers Trail Builders have experienced, some people think they can do whatever they want without permission. This trail is on land owned by the Salisbury City Park. There is this thing called LIABILITY.  A person interested in making changes can talk to the Park Manager or any of park staff at that park (someone is there full-time) and they will give them my contact information. This jump will have to be altered, maybe dis-assembled.  Also, this small creek gets up considerably in a heavy rain and dissipates quickly.....the jump will be washed away.  I sometimes walk the trail after heavy rains to see how things are temporarily affected. 
This person is probably interested in a one time "build" but is not aware that it will be washed away and later require maintenance by someone other than themselves.  We want to make additions of "fun and challenging things" to the trail but it is difficult to get people to help. Changes to the trail must be controlled.  Help is always needed. With this said, I sincerely ask that the person that made the jump call me at 704-639-0009 and I would be happy to get with him to make long lasting changes, berms, banking, jumps or whatever.  I'll have to say I like people that have energy and a willingness to work on the trail.
