As I'm writing this, it is about 6 hours since I accomplished this feat and I'm still in shock!!
What did I do? I converted the Big 4 Split!! I've never seen anyone do this before and now that I've done it, I can still say I've never seen it. I thought I had missed it so I wasn't watching!
For those of you who don't bowl, here's a bit of information. The standard setup for bowling pins looks like this:
After I threw my first ball, these are the pins that I had left:
I hit the 2 pins on the right, causing 1 of them to slide over to the left and hitting the back pin on the left which fell forward and knocked down the front, left pin.
Out of the 1.5 million achievement awards that the US Bowling Congress gave out last year, only 2,130 of them were for converting this split!! (source: USBowler magazine, winter08-09 issue) Now I get one of these awards too!!
