Sounds like you made it around all the trails, plus some extras. One of the sections that you rode is off limits to bikes, but you wouldn't know that because the sign and map were stolen. Sounds like you enjoyed most of the trail except the section that is currently being worked on and the log piles (some of which will be removed; others have just settled).
Every issue that you mentioned could be addressed with a little more help during trail days. Currently most the work is being done by myself and a couple other people. I would like to get a Kiosk built and trail signs put up, but I also need to keep pushing the trail forward. We are getting closer to the end of the red loop and this last section is going to be great when finished. See this post for information to help during the week http://www.mmba.org/forum/viewtopic.php?f=40&t=90601
. I'm also planning for another weekend trail day.
