Centennial Group Meetings

Outing: Bike Ride on the Silver Comet

Date: October 26, 2014
Time: 9:45 AM at Silver Comet Depot
4342 Floyd Road, Mableton, GA

Join us for a leisurely ride east from the Silver Comet Depot past Mile Marker 0 to the Silver Comet Extension and on to South City Kitchen restaurant in Smyrna. We'll arrive at the South City Kitchen in time for brunch after which we'll return to the depot. 
The Silver Comet is a multi-use trail constructed on an old rail bed and is mostly flat. Our riding speed will be in the 8 to 10 mph range (easy).  We'll meet at the Silver Comet Depot (4342 Floyd Rd SW, Mableton, GA 30126) at 9:45 AM and leave promptly at 10:00 AM.
As part of the ride Roberta Cook, founder and coordinator of the River Line Historic Area will give a brief talk about the effort to connect the Comet to the Atlanta Beltline, and show us where the connection will be made to the existing trail.  This connection will make it possible to take the Freedom Parkway Trail from Stone Mountain to the Beltline over to the Silver Comet to the Alabama state line, then continue on the Chief Ladiga Trail to Anniston Alabama, among other options.  In a larger sense this connection will transform the Silver Comet from a recreational trail to a fully functional transportation asset, a truly exciting possibility for many cyclists.
It’s a chance to enjoy some for fresh air, excellent food and to connect with people doing their part to make Atlanta a cycling friendly city!  To learn more, and to sign the petition to build the connection go to Connect the Comet.

  •  Helmets are mandatory.  No helmet, no ride.
  • This is a leisurely, no drop ride, about 5.8 miles one-way, 11.6 miles round trip.  There is one short, nasty hill just past Mile 0, but it’s OK if you need to walk up it.  The good part is that hill is a downhill on the way back, no need to pedal your breakfast up a hill!
  • The only downside is we do have to cross two busy intersections, but they do have pedestrian crosswalks that we’ll use.  The rest of the ride is on dedicated multi-use trail.
  • A small tool kit and a spare tube or patch kit is recommended.
  • There are bathrooms and a water fountain at Silver Comet Depot.
  • For anyone who would like to look at the menu at South City Kitchen: http://vinings.southcitykitchen.com/menus/brunch/
  • Please make sure your bicycle is ready to go and that you can sustain 8 – 10 MPH.
  • The ride will be rescheduled if rain is forecast or the temperatures aren’t forecast to be above 40 degrees by 10:00 AM
  • If anyone would like to get a little more mileage I'll be getting on the Silver Comet at the Carter Road trail head and riding to the Silver Comet Depot at Floyd Road.  Please PM me for details if you’re interested in this option.


Atlanta Beltline Tour - Saturday November 1, 2014

Join the Sierra Club for a bus tour of the Atlanta Beltline project. The Beltline project proposes to create a network of light rail transportation encircling the city of Atlanta. The proposed route will join many of Atlanta’s older neighborhoods and industrial brown sites and act as a catalyst for new, multiuse development. It’s a great opportunity to see all of these old neighborhoods.

The bus follows the route of the beltline and a guide will describe the Beltline concept and history, project planning, and implementation. The tour takes three hours and includes a rest stop in West End and a walking tour of the now defunct Bellwood Quarry in Northwest Atlanta.

The tour departs from the Inman Park MARTA station, located at 1055 Dekalb Avenue, NE, Atlanta, GA 30307. To sign up or for more information, contact Bob Springfield at bob@bobspringfield.com or (770) 365-9440. Limit 15 persons.
