Biking and Walking to Work

Bicycling.com came out with a ranking of the top US cities for bicycling.  I took their top ten cities and dot mapped every commuter in and around them, colored by their method of commute, to get a visual sense of the density and dispersion of biking and walking commuters around those cities.  A more topically specific and geographically general look at commuting data than these maps of Seattle.
So blue people-dots show bikers, green people-dots show walkers, and gray people-dots show all other commuters whatever that method of locomotion may be.

The diaspora of pedaling and walking to work, for bicycle magazine's top ten bike-friendly cities.  Poster.

Caveats:
1. The relative geographic scale between these insets is varied.
2. The people-dots are randomly distributed within their home census block groups -you'll get the occasional commuter in the water, etc.  So have fun pointing that out.

And here is a slippy slappy version...

Unfortunately, the data recorded no distinction between bicycles and unicycles, so quirk-rich neighborhoods are obscured -for now.  Nor were old timey bicycles flagged, but I'd certainly be interested in a map like that, which I presume would show strong collinearity with handlebar mustaches.

Check the map for source links.  Also, I'm pretty excited about finding a sweet sweet collection of every DOT signage icon in PDF and EPS formats, which is where my bicycle and walking dude came from.  Gold.
