Just found this on Commissioner Jeff Rader's site:
There are more of the popular “Walks in Mary Scott Nature Park” coming in early 2012. The walks are at 10 am on the last Saturday of the month at 4150 Briarcliff Road (just north of the intersection with Shallowford Road.) Walks are FREE, offered rain or shine, and last approximately one hour in length.
