When I pull the blow downs off the old fall line trail again, leave it alone. There's nothing wrong with it. MCPC doesn't care and I suspect if I brought your unsanctioned actions to their attention it would only work to diminish your reputation and standing.
@GJ11, at this point (and as others have recommended) you'd be best contacting MCPC. They can validate everything I have said. I will PM you the Trail Foreman's name and number. I hope that your talking with him will put this issue to bed and we can all move on and that anyone who isn't happy with the closure of the old section will accept this. Know also that we are always looking for volunteers to help improve the trails and, fingers crossed, build some net new ones.
