Cargo bicycles

I'm traveling for a couple days and am in Sacramento for the national Association for the Study of Peak Oil (ASPO) conference. Maybe it's odd for peak oil advocates to travel from around the country to meet, who knows, but I chose to travel without driving. The conference is in Downtown Sacramento and there is an Amtrak station right in downtown, and it's relatively easy to get to Amtrak from my home, so I walked to the train station, dragging a small bag with my clothes, rode the train, and then walked the 1 block from Amtrak station to my hotel.
