20090930 Four Loops by akamediasystem published on 2009-09-30T21:43:56Z I walked four times around the same place. Four loops. I was wearing binaural microphones. Even at the same place, the sound is never the same. But it is often familiar. I geologged as I walked. The geologging and the recording were started simultaneously. <a href="http://maps.google.com/maps/ms?ie=UTF8&hl=en&msa=0&msid=100211940629798814607.000474d2d2e9ab8832776&z=18" target="_blank">Here</a> is the map of the walk.
