Hey Tank 03,
That A-10 you and your buddy saw might have been from either the 104th FW MASS ANG or the 103rd FW CT ANG (my unit), but to go that far north without an in-flight refuel or drop tanks (which we don't use on local flights) wouldn't work. I also thought he might have come out of FT Drum in upstate NY ( we go there for target practice), but he would still need extra fuel. The only thing I can think of is he landed at a local A/P, refueled and had some fun before heading home.
It's great you and your buddy were able to witness that, A-10's look pretty cool when they're put thru it's paces. When I was active duty Air Force in the late 80's stationed at Eglin AFB, Fla., myself (as a young airmen) and a sergent were transporting slabs of steel to one of the gun ranges when we were buzzed by an A-10. He made a head on pass at us, he was so low I saw the pilot BEHIND THE HUD. We never heard him until he was on top of us. THAT WAS COOL!!!!!!!
