I apologize for the 100 yard comment.  I was basing this on personal
experience, and had not thought of people using high gain antennas.

In SF. In the hills, the DOC was able to use a directional antenna to hit
networks over 20 miles away.

You might want to re-think the 100 yards statement, 802.11b has a
theoretical limit of 21 miles. I know of wireless hotspots that can be
reached from almost a 1/4 mile away without any external antennas on the
unit. Add a decent directional antenna to the unit and a clear line of sight
and your easily talking hundreds of yards.  
Granted most wardrivers are going to be close to your perimeter, that will
not always be the case.
