Y'know, I like that idea more and more.
I can see an event that'd combine a few things here:
1) Food, ie: lobster/clambake, harvest-type goodies, BBQ or the like,
2) Demonstrations, ie: tractors/threshers, the sawmill at Alna Ctr, antique engines; steam AND diesel, maybe even atique autos and firetrucks etc.
We see stuff like this at the picnic, why couldn't it show up again around harvest time?
And there's no reason it need be a huge "Fairground-sized" event either, NOR would ALL the action need be at AC. There's plenty of room if you spread stuff out at both locations.
Hey, maybe the threshers display could help sell the idea to Mr Albee by haying his field for him.
All just thoughts.
