Deb Hubsmith, a cycling zealot whose political savvy blazed many North Bay bike paths over the past 13 years, will step down as advocacy director for the Marin County Bicycle Coalition to focus on the national Safe Routes to School program she founded.

Hundreds of joyous Marin County cyclists pedaled through the Cal Park Hill tunnel Friday afternoon as officials cut the ribbon on a $27 million holiday present that supporters hailed as a national model for green transportation.

After 17 years of planning, the Cal Park tunnel will open to Marin County cyclists today, providing a shorter, safer route between San Rafael and the Larkspur Ferry for an estimated 800,000 riders a year.

Marin County's ribbon cutting and celebratory ride Monday in the Alameda del Prado bike lanes - a long-missing link in the county's North-South bikeway - was followed by the revelation that landscapers used a weedkiller banned under the county's strict pesticide law.

Talk of a one-dollar tax on rental bikes in Sausalito is fanning long-simmering tensions between the picturesque city and the local cycling community.

Amalia Pittier of Caracas, Venezuela spent a sunny day riding a rented bike across the Golden Gate Bridge to Sausalito with her two traveling companions, stopping to buy lunch and spend money shopping for gifts they will take home to family and friends. Little does this tourist know she's at the center of a local controversy because she and her friends are among the estimated 250,000 visitors annually who rent bikes to ride over the bridge for a day of sight-seeing before they climb on an evening ferry for the return trip.

Within a few weeks, there should literally be a light at the end of the Cal Park tunnel for cyclists commuting from San Rafael to the Larkspur ferry. Engineers are mucking out dirt and boulders on the collapsed south end of the 1,100-foot tunnel, making room for an 11.5-foot wide bike path and tracks for the SMART commuter rail trains.

A large and divided crowd turned out last night in Marin County to help decide whether the long-neglected Alto Tunnel between Mill Valley and Corte Madera should be reopened to cyclists.

Cycling enthusiasts have long dreamed of reopening the rotting, 125-year-old Alto Tunnel as a key link in a greenway stretching from the Golden Gate Bridge to Cloverdale. Now they may get their chance, as the county's Non-motorized Transportation Pilot Program begins a $225,000 study of three routes between the two southern Marin towns.
