Midtown resident and cyclist Lou Heinrich cares about the American River Parkway. He cares so much that earlier this year he came up with an idea: sell cycling jerseys and give the profits to the American River Natural History Association, which operates the Effie Yeaw Nature Center. Heinrich reasons that by supporting the nature center, you are in turn supporting the parkway. “By doing this, it is relieving the parks department of this expense (of taking care of the nature center) so we’re supporting all the other functions of Sacramento County Parks and open space, especially the rangers,” Heinrich says. The jerseys were designed by Brian Clifton, who also designed jerseys for OneSpeed, and cost $99. You can purchase them at the following local cycling stores: Rex Cycles, 1811 E St., Sacramento, (916) 446-5706; City Bicycle Works, 2419 K St., Sacramento, (916) 447-2453; Carmichael Cycles, 5142 Arden Way, Carmichael, (916) 488-5353; and Whitworth Cycles, 2311 S St., Sacramento, (916) 457-7247; as well as at the Effie Yeaw Nature Center, located inside Ancil Hoffman County Park, 2850 San Lorenzo Way, Carmichael, (916) 489-4918, and through the American River Natural History Association’s website. But here’s the rub: Heinrich says the retailers only have left smalls and mediums for women and smalls, mediums, larges for men (no more extra larges). If buying a jersey is not an option, Heinrich suggests another way to support the parkway: buy a parking pass, which costs about $50 and is good for a calendar year. “The most important thing you can do to support the parkway is buy a parking pass,” he says. Parking passes are available online or at REI.
