As trail steward at Blue Mound, I'm undoubtedly biased on this topic, but here goes:
CORP, as a builder of trails is under no obligation to construct trails that are suitable for any amount of speed. It is the responsibility of the rider to use the trails with his bike under control at all times, without exception.
If you think about it for more than a moment, it can not be any other way. No matter how carefully we work at creating safe trails, someone can *always* ride them faster than they are able to handle. CORP has no way to force you to ride within your ability. The safe use of the trails depends on the riders' judgment. Always has, always will.
That being said, I have confidence that Josh and Chuck will do their best to deal with the situation the OP described to find the best compromise between flow, safety, and trail sustainability. FWIW, everyone inside the club is aware we need to find the resources to do a better job with trail construction and maintenance. We're working on that, but the solutions aren't cheap or easy, especially across multiple trail systems. As Chuck states, at some point the solution involves moving a lot of dirt, maybe more than we're currently able to do. The OP's offer of help is a great response and much appreciated.
