This will be a 23-mile ride to several points of interest in the Redland, including the Flea Market, Whitneys' Produce, Castellow Hammock Park and Knaus Berry Farm. The ride starts at 10 a.m. from 20500 SW 112th Ave., right off the South Dade Trail (busway path). For more information, write to ride chairman Gary Mendenhall -- gary@greenmobilitynetwork.org.

Look for Green Mobility Network's tent, and many other Earth-friendly vendors and exhibitors, Saturday morning, the 6th, at 405 Biltmore Way, opposite Coral Gables City Hall.

Everyone's invited to hear Peter Wood and David Henderson speak on how the environment we build can affect our health as individuals and as a community. There also will be an update on the local response to bicyclist Christophe Le Canne's death last weekend on the Rickenbacker Causeway. We'll meet at the Gwen Margolis Community Center, 1590 NE 123rd St., North Miami. There's no charge.

Many cyclists and maybe some runners will convene Sunday on the Rickenbacker Causeway in memory of Christophe Le Canne, the cyclist who was killed on Bear Cut Bridge earlier this week. The group plans to meet opposite MAST Academy, start for the bridge at 9 a.m. and there pause respectfully, then ride on to Key Biscayne village and back.

There are three things that ought to be done right now, before our tears dry over the loss of Christophe Le Canne to a hit-and-run driver on Sunday morning.

• The authorities need to lower the speed limit on Crandon Boulevard to something reasonable for a road that regularly has thousands of recreational users daily -- beach-goers, boaters, runners and cyclists -- not to mention Key Biscayne residents driving to and from their homes and jobs. While those wide lanes invite speed, this is not a highway but an urban street.

We welcome Kaelsie Saravia to the board of Green Mobility Network, and congratulate Gary Mendenhall for taking on the job of ride chairman. We are fortunate to have their support. If you have ideas for them -- or any of our leaders -- I encourage you to click "contact" above and use the pull-down menu that suits your purpose.

Kaelsie is a designer with Surface Workshop in Miami, and a green-thinking architect who immediately saw the potential of our mission when we met her a few weeks before Green Mobility's founding caucus in 2007. You may remember her showing up at City Hall to speak on bicycle issues, or pitching in to help with bike valet.

Gary also has been cheering us on from the beginning, quickly volunteered for bike valet and other projects, and organized our successful M-Path rides over the past several months. He's on the sales team at J&B Importing, and was part of Florida's delegation last year to the National Bike Summit. He commutes by bike and loves to go out on weekends for an alley cat race or a mountain bike excursion.

Adventure Cycling leader Jim Sayer challenged a roomful of members and other cyclists last night to join the push for Congress to make bicycling and walking a higher priority in the next national transportation bill. While his group and others are busy in Washington, he said it's local groups such as Green Mobility Network and the Florida Bicycle Association that are best able to awaken members of the House and Senate.

The new TACOLCY Bike & Safety Club makes its delayed with a 15-mile neighborhood ride from Tacolcy Park, 6161 NW 9th Ave., Miami. You're invited to this kid-friendly event, postponed from Jan. 9. For information phone Roger Horne at 305-751-1295.

Thanks also to all who backed and encouraged our work through the past year. It's not too late to join or donate to carry our work strongly into 2010. See the yellow buttons elsewhere on this page. We wish you good rides, good health and ever-better streets and trails for South Florida.

It required just four city parking spaces to hold 50 bicycles when a crew of Green Mobility folk looked after movie-goers' bikes Saturday during the Bicycle Film Festival in Miami Beach. Thanks to the city Parking Department for making the lot space available.
