My name is Jim Kalafut and I live in Peoria, Illinois. I was introduced to OSM via an episode of FLOSS and am quite hooked. I work with GPS professionally, have done some Geocaching, and am a big proponent of community projects such as OSM.
Most of my mapping is in the Peoria area as there is a lot of work to be done. Keep an eye on the Peoria wiki page for progress reports.
