Hey Steamer, Manny will chime in on exactly where he was but it sure looks to me like just on southeast edge of town on Cheese Factory road (off Myers rd) then out crossing Maple Manor drive on the way to Brandford/St. George. Great area, not too travelled and very similar to many backroads in the golden triangle area.
There is a 'Dub' now is on Hespeler Rd, (Galt) (and moved a few times over the years) and still has cruise nights every week.(Thursdays I believe).
Downtown Galt has one I think on Fridays next to the river which is fun too.
Glad to have made contact with someone who once lived in the area. It's very special to us and quite a beautiful place to live.
