In order for us to recognize each other on this busy occasion i think we should have a special hand signal to identify ourselves to fellow geo-expaters.
I will be the one of the guys dressed in shirt and pants.
The signal will be to take your index and thumb finger into a hole, then sticking your other index finger (in n out) of the hole.
If i give you a confused look just say the secret phrase "I'm looking for some hot beef."
