Warbiking home yesterday evening. Had to fiddle a lot with the gps unit to make it find itself. On the way home kismet discovered 191 wireless networks (the other 18 on that list are clients seeking their network) and managed to map the location of 173 of them. I fiddled a bit with waypoints in gpsdrive (seems it can't display 173 waypoints at the same time) and managed to create maps of the access-points found. Map 1, Map 2, Map 3.
