Those who regularly ride Turnbull Canyon may already know what's going on there, but for those that don't, it seems like there's an all out assault on mountain biking happening as we speak. First, a couple of months ago, there were large rocks placed on the several of the switchbacks commonly known as 7th Street. Going down, this isn't a huge deal, but it's now very difficult to go around them while climbing the other side. Now, according to the Facebook page for the Puente Hills Habitat Authority, bikes will no longer be allowed to ride on the trails referred to as the Hellman Trails, which means A-Line is no longer accessible to bikes. (Note: the "Hellman Trails" have been closed since January for repairs after all of the storms destroyed the trails) I have rode these trails for over seven years and this is really disappointing and disturbing to me. The Habitat Authority owns all of these trails, so to me, this is first step towards the end of mountain biking on these trails. Maybe I'm just being paranoid. Now that I've vented, here's what has been on my mind: - I don't know the first thing about trail advocacy or how to proceed at this point - I can make phone calls or send emails, but do I say? - There seems to be a much larger, organized, MTB advocacy in Orange County. Is there a MTB group out in this area? I'm looking for ideas at this point. Thoughts?
