I used to live in portland, and i'll contribute to this page once in awhile still.
Debian is my operating system of choice, and light laptops are great for WarWalking.
I used to like building my own AshlandWireless:PvcYagi antennas. But, cans work better/just as good, and are cheaper, and less time consuming. The only other type of antenna I would continue to mess with doing homemade, are helicals, damon and I have had excellent success with these.

I COULD put a picture of me here, but honestly, wouldn't you rather see my velcro setup with my IbmThinkpad X20 and my Superpass SPDG11T sector antenna, that I use with kismet?
