I'd rather not share our stumbled files for one reason:
I don't know you personally, therefore your intentions are unknown. We are gathering this info for analytical reasons only. *Dubious* or otherwise casually-prinipled individuals could use the information we've gathered for illegal activities. tsk tsk.
However, we are keeping our maps up-to-date and even though they do not show you any usefull information, you can judge by our maps what areas will be most fruitful to your Sunday drives. For example, two hours spent in the Arlington area will produce over 300 networks. The same goes for the D.C. area, west of the Capitol.
We have a "big map" that shows the entire area we've covered, plus we've broken down several *session* maps of specific area's we've covered.
All maps we have available:

Only for the "Big Map" and some interesting stats:
