Two more carts are just about to roll off the "assembly line" , outfitted with fashionable blue and red wheels. Those are available at no extra cost, along with the traditional silver or black wheels. Please also note the difference in ground clearance on those two models. The blue-wheeled cart has lower ground clearance for smoother dirt trails, whereas the red-wheeled one rides higher for rougher terrain.
We'll join the "Urban Mushing" group (http://www.urbanmushing.com) on Saturday morning at San Diego's Marian Bear Memorial Park: http://tinyurl.com/6bwoyk at 7.30 am. A cart will be available for try-outs (byod).
