I'm in the Twin Cities area, John, I think about 100 miles from Duluth. I get up there sometimes, it's a great place to visit/vacation, being a Great Lakes port and all.
Wayne, it's even worse than it looks; there's another 15 or so hanging out in the garage, my "mothball fleet". Most of these have engines on them too, so I have engines that haven't been run in (literally) years--just can't get around to them all.
When I was a kid I didn't have this problem...pretty much one plane at a time. Engines too. Even when competing in my teens/20s, my brother and I maintained only 3 engines--a .40 for Rat Race and 2 .35s/.36s for combat. We smeared the .40 all over the asphalt at Lubbock once (left a hole too), so pressed the .36x into service for Rat as well as combat. Then my favorite old Blackhead .35 blew up, so we used that same .36x for all of our 4 entries in Rat/combat, spent all our time between matches/races frantically switching it from one plane to another. Hardest part was re-needling it each time for bladder (combat) or hard tank (Rat). That was one tired engine when we got home. We invested in a few spares after that.
Now I have a can full of engines that have never been run even once. Times do change.
