Consider these photos an addendum to my hiking column on the 2.5 mile paved Buhl LakeTrail of Addison Oaks County Park that appeared  in the Oakland Press on October 17. Last week I hiked that trail with other participants of the 2010 Oakland CountyTrail Summit.  Most woodland trails in Oakland County are now at their peak color so get out and hike: just don't step on any rattlesnakes,  for our shy massasauga rattlers - our only venomous snake - are catching the last rays of warming sunshine, sometimes on the dark surfaces of trails! The building pictured here is a tudor style conference center; the mushroom a shaggy mane: both are trailside at Addison. For information on all Oakland County Parks: http://www.destinationoakland.com/  Autumn is fleeting with the first frost  just around the corner. In the not to distant future my Earth's Almanac blog will be exploring a world of snow adventure and winter wildlife.  (To discover the trails of the Huron Clinton Metropark System connect with http://www.metroparks.com/  And be sure to check your local town or city for their trails! Stay tuned to the Sunday Oakland Press http://www.theoaklandpress.com/ for hiking tales and locations to hike across our county; the column appears in print and on-line.)
