I took my handheld GPS receiver with me in London, where it and OpenStreetMap data were invaluable at navigating to wherever I wanted to visit. I left the track logs enabled so I have a crude map of where I went in London:

Parts of the Thames are visible.

I also attached it to the buggy of an unsuspecting victim kite flier at Wallop which produced this track:

Red parts are slow, green (turning to blue) parts are faster. The maximum speed was 36 MPH.
