You sure that was not Baildon, South of the Jaw? They had an annual event there.I wish I had a better memory... west of MJ there was a town with a museum that I thought did some heritage days, it is where I fell in love with hit and miss engines. But I can't remember it. Every time I drive the transcanada thru SK I keep trying to recall where they heck it was so I can stop but no such luck. All I see off the highway is a thick legged disproportioned cement moose.
Eight (more or less) years there, and I cannot recall anything of that sort happening WEST of there. Caronport was mostly religious, and not real in to community shows... Hells, you were rumored to have to be cleared by the 'church squad' to be able to buy there...
The Western Development Museum IN Moose Jaw, was a pretty cool place though! The WDM in PA was also worth a look, as was the one in 'Toon Town!
