I used to be an IPSC addict, but it's been a few years. Most of my shooting was done back in the 90's and early 2000's.
My local club was a bit looser than some. They would have the standard, sanctioned set-ups for scoring. But then often added a few "optional", fun stages. Often with very high round counts, stairs, windows, and doors.
I still remember one from way back, the match fell on July, 4th. So the "bonus" stage was appropriately named "Independence Day". It took every magazine I owned, which were stuck in pockets, all around waistband. Some guys and gals had to get VERY creative where/how to tote mags. And I can honestly say that it was the most memorable shoot I've ever participated in. What a blast!
