Glide church needs volunteers. Not today, though the spots on the popular Thanksgiving food line filled up weeks ago (though donations, including food and toys, are always welcome). It seems that just as many people want to help Glide as want to pick up a plate of Thanksgiving, which is one of nice things about living in a place like San Francisco and going to a nice place like Glide. Although the volunteer spots are gone, you can still enjoy a meal if you need to the church expects to serve more than 7,000 as well as attend the Thanksgiving Day Celebration service, one of its signature everybody-into-the-pool extravaganzas. If you're really in the giving mood, join Glide founder and Minister of Liberation Cecil Williams, Senator Dianne Feinstein, Janice Mirikitani, and Willie Brown on Dec. 18 for Glides annual holiday festival, Celebrate Home, which takes place around the corner in the just-shy-of-the-Tenderloin O'Farrell Hilton. As for you eager volunteers, many of the holiday events are already booked, but there's still room at the big ones, with shifts available for Christmas Day and the many post-Christmas meals. Hurry and sign up online.
