Anthony,
Speaking as one of those "gentlemen" already signed up to play at Long Cove among others, thank you for the idea of getting together for an unofficial get-together.
However, I want to let you know that the folks who put these meetings together tend to pack about a months worth of presentations, golf outings, cocktails and dinners into four days time. This typically leaves little extra time within those four days for outside activities (if one sticks with the "official" schedule). Yet, some do come a little early and/or stay a little later which would leave availability to do what you suggest.
I'm sure those individuals will get in touch with you if they can do that, and last time I thought about this, there are actually quite a few ASGCA-types who troll about on this discussion group:
Jeff Brauer
Forrest Richardson
Jim Lipe
George Williams
Rick Phelps
Ian Andrews (soon to be)
Todd Eckenrode
Gil Hanse
Ron Kern
Tim Liddy
Art Schaupeter
(apologies to anyone forgotten)
