I don't know if anyone else is doing this, but I've started tweeting trail conditions using hash tags.  For now, I've created #FalconTrail and #RidePalmerPark.  (Apparently, the hash tag 'PalmerPark refers to a rather rough neighborhood somewhere, not sure where...).  Anyway, the thought I had while negotiating Falcon Trail was to keep riders up to date on trail conditions in the Pikes Peak area.  With winter approaching, it'll be nice to keep up on the freezes and thaws.  It could also be used to tweet trail work, trail issues, etc.  Just another way to use social media, I suppose.
