Yes, this was Gregg (with 2 "g"s).
Gregg owned the Spencer Airport, was an A&P/IA, CFI and would do anything for you. I saw him on Saturday at a Christmas party, and drove him home. His wife and ten year old son had left earlier, and he didn't want to leave yet.
I bought my Cherokee ten years ago, and inquired at the Worcester Airport about keeping it there. The produced a mountain of paperwork to be filled out. I then stopped at the Spencer Airport to inquire there. There was no paperwork to sign, just go in at the beginning of each month, find my gas slip, and drop a check on his desk. When I inquired about insurance (Worcester was to be named as an additionally insured $1 million policy) Gregg said "Don't hit anything".
When I was out of work, Gregg hired me to help him in the shop. He taught me how to remove inspection plates, how to do brakes, oil changes, and lube pulleys. There was no bill when I picked up my plane from annual that year. I traded my work for avgas, and never flew more.
Gregg was at my Labor Day party one year, and my dog attacked him. Still unknown why, but he ended up with four puncture wounds in his little finger.
A few months after I bought my plane, I learned of the Lycoming oil pump AD, and ended up having Gregg overhaul the engine. Actually, Mattituck overhauled it, but Gregg removed and installed it, along with all the other associated stuff. I found Art Mattson's STC for the 160HP upgrade. A few months later, Howard bought a Cherokee, and pretty much did exactly what I had done, including Mattson's STC.
Gregg died in Howard's Cherokee.
I hadn't been flying my plane much, and ended up selling it about a year ago. Gregg handled the sale (I found the buyer on eBay), and mailed me the check. I hadn't seen him for a while, but swapped emails with him.
I got an email from him two weeks ago, inviting me to a Christmas party that Harvey (another Cherokee owner) was throwing on Saturday. I'm really glad I went.
