If you like old power equipment, steam engines, hit and miss engines.   This the show for you.
August 4,5,6 on their grounds on Co.HWY B west of Hwy 26.  
It looks like this year they are having a hammer in on the grounds for blacksmiths.

We usually spend a day there every year. We walk around for a few hours then take a rest watching the tractor pulls or steam powered sawmill.

I took my 4 yr old Grandson to the Power show today.   He saw his first tractor pull, was not impressed.   He saw a Blacksmith.   Saw some steam engines and a steam powered saw mill still not really impressed.  What did impress him was a small hit and miss engine powering a 3 piston water pump.   Seeing the pistons going up and down the crank shaft spinning and the belt drive spinning the pump was what he really liked.   I think it was the size.  The engine and pump were right down at his level.
