For all road warriors, I can’t think of a better rule of thumb — carry a bike in the back of your hybrid, H2 or whatever. It saves gas, saves the planet, infuriates cabbies and gets you where you want to go most economically. Last night I road up and down 6th Street several times and in the Warehouse District to check out the SXSW flava. There were stops at Peche … 6 … a PBS artist showcase and more. Ha … I even infiltrated a local mountain bike gang as they road wheelies into the night. Here are a few highlights, including bluegrass busking to keep Austin unWired.
