I was riding west on 4th Street (the same 4th Street many of us in Los Angeles hope will be the city's first real "bicycle boulevard"), when I saw a fellow riding along ahead of me pulling a trailer.
Nothing unusual in that; but when I caught up with him I saw that he was pulling the trailer with an Xtracycle!
I am always glad when someone shows that the need to haul lots of stuff is not an argument against practical cycling: better an Xtracycle and trailer rig than an SUV, after all.
But in a world where Americans' hyperactive acquisitiveness is responsible for so much environmental, social, and political degradation, perhaps a better primary message would be that bikes are practical because you don't really need so damn much stuff.
So I'm torn between admiration and a slight touch of despair....
