Andy Stacy wicks it up

Here's Andy Stacy getting air on his big Katoom, riding for George Quay's Keystone Engineering race squad. Andy used to stay at my place north of Atlanta.  Loved having the 3-digit guys hang out and work on their bikes.  I was a 3-digit sort of guy.

The entire Stacy family treated me like gold.  Great upstate New York individuals, nice friends to have.

So my memory is slipping...someone help me fill in the blanks.  What year (1981?) and what race facility?
