Mapped walk

I took the kids for a walk this evening (them in a stroller, me pushing), and I brought along my GPS. I happened across a cool website a few weeks ago - it'll overlay your tracks on a variety of maps (USGS, TIGER, topo, Google, etc.). The picture shows where we went, with the altitude color-coded (red is low, purple is high).

The site is called GPS Visualizer, and it's run by Adam Schneider. If you've got a GPS, check it out.
