A couple of weeks ago, while I was on lunch break I went and recorded the downtown Topeka 2001. Being the first of the month they tested the sirens in Attack. Figured I'd post the video. Has a little bit of nice echo. I really don't know why they didn't place it ontop of the building the old Thunderbolt is on, as downtown Topeka has some tall buildings the sound waves might not carry around.
