Ron Ucovitch (a former Sierra Club leader) leads hikes on most Thursdays.  His   hike is in Sibley Volcanic Preserve.  I especially like the potlucks.  I have been hiking with Ron for over 10 years and his hikes often give you additional knowledge about the history or the park.  He is also the guide for USS Potomic Tours out of Oakland.  If interested in Thursday walks, let me know
