What was the craziest location that you made an audio purchase from?

Working in The Sears Tower (mid nineties), got the bug for some MM cartridge which was available at a small Hi-Fi shop in a western Chicago suburb. Took the train after work and was dropped at a small commuter station about a mile from the store. About a foot of fresh snow on the ground through which I walked in my dress shoes and pants. Made the purchase and caught the next train back. It's a rough hobby but someone has to do it.

A bar on Maxwell Street in Chicago on a Friday Night when I was in college. 

I bought some good cheap banana plugs in Bangkok Thailand.

Twice while driving up a windy road eating griild fish with chopsticks and reading the Darwin awards I rang up my Guru and ordered four Schumann Resonance Pulse Generators. The car was a rental from Hertz and was a bargen for $7.83.

I bought some speakers used on usaudiomart from a guy in upstate NY. 10 hour round trip, but totally worth it.
