Strewnfield maps

Hello to you all. I'm new here and need help from you experienced people.
I'm new to MD and to meteorite hunting, which is what I got into MD for. I've googled and yahooed myself sick, and found many sites that describe meteorites and some have photos of found meteorites. But I can't find any maps of strewnfields so I know where to look.
Do any of you experienced folks have any suggestions on where I can find strewnfield maps, especially for Arizona??
Did a google search for Arizona Meteorites and found the below site, if you use google earth you can save the map and make a transparent overlay. Then you can zoom in from Google Earth and narrow the location down and even get GPS coordinates by adding a placemark using google Earth and sticking it in the center of one of the blue star meteorite maps marks.
