I have but that was over 10 years ago and not a big event by anyone's standards.
There are some real players on here (with + handicaps and current/former touring professionals...I'm not one) The closest I ever got was the PAT and was so excited about that I stuck my foot in my mouth one day in the wrong company. Oops.
Nowadays playing 2 dozen rounds a year I just don't want to see 80+ on the card.
Glad you found what you were looking for. Have fun! Pay attention to what's going on around you and bring your best etiquette as far as on the course goes. Act like you're always being recorded since you probably are.
Above all have fun. Did I mention have fun?
