Bike room glut: blame the cruisers!

I see cruiser bikes all over Capitol Hill.  The problem is that they're never actually moving.  Instead they are locked up (and usually rusting away) or clogging up apartment building bike rooms.  Unless your entire life is isolated to a few north-south streets, our hilly 'hood is less-than-ideal for cruising around in a steel tank with limited gearing.  So why are there so many cruisers clogging up prime bike parking real estate?  Do all of those California transplants drag their beach bikes with them when they move?  Or are cruisers one of those impulse buys that "seemed like a good idea at the time"? 

p.s. J, just a thought, but how about adding some questions to the census to empirically test this.  e.g., "What kind of bike do you own?" and "How often do you ride your bike?"
