I'm from the midwest and until recently I had enough Slipknot shirts for everybody.
Seriously.
They were from around 1996, when the band won a spot at a local gig called Dotfest. Slipknot was in no way a big deal yet; Everclear and the Specials were the closest things to a headliner the show could manage, but my gf at the time was a big Everclear fan, so away we went. Anyway, some idiot who must have ran their li'l impromptu merch booth left a decent sized box unattended by his van, so I stole it.** Turned out to be a couple dozen beer soaked Slipknot shirts. They populated my paint rag bucket until fairly recently.
*Disclaimer: Cut me some slack here, we were 16. Also, this trip is the origin of my Art Alexakis Is A Dick story.
**Disclaimer: The 16 year old Whipstitch was a dick. I typically disavow knowledge of his actions these days.
