Played at Twin Oaks back in college in the summer, and I've been playing year round since I moved down here. Most of the time I have to agree that a great defensive play is the best. Throwing a guy out at the plate, or who is trying to go first to third gets me all "GOOMF! Who are you trying to run on!"
Although my finest softball moment came when I pulled a hamstring playing in a tournament in like 150 degree heat. Our team had to take an out the next time I was up (kind of a fp I guess), but in the last inning, with two outs I had to hit. Knocked a line shot into LC that plated the winning run. Hopped to first base on one leg pumping my fist Kirk Gibson style.
I umpired a ton of baseball, girl's softball back in high school college. Pretty cool job, except that it was pretty easy to work a whole lot more than I really wanted to. I don't think I could have beat the money at the time though.
