There are many things that seem quintessentially ~Portland~ to me, on very little evidence. Maybe they are just things of our times, and this is when I happen to live in Portland.
One is the harnessing of little toy horses to those old rings in the sidewalk that are generally thought -- correctly, I think -- to have been put there back in the day for the harnessing of actual horses.
I generally like this custom, at least while the horse in question is still in good shape. They eventually get pretty shabby.
The other is the presence of very tall custom-welded bicycles. These are, I suppose, real creative and technical achievements on the part of the people who craft them. Nevertheless, I must admit that I think of these as "asshole bikes."
The L&TM5K readership spans literally several cities and more than one country! Tell me -- do these phenomena exist in your place of residence? Or are they unique to the City of Roses?
