In the States, my wife and I both liked malted milk shakes. When we came to Canada, they only had milk shakes; no malt. Malt was hard to get since it was included with some yeasts and other ingredients that were forbidden because they were used in illegal home made liquor and beer.
Canada was a peculiar place back in the 50's and 60's. There were beer parlors, filled with men, women not allowed. In some towns, women went to one room, men to another- no mixed drinking allowed.
Alberta had a sky pilot for premier for quite a spell.

We still like Brown Cows and make them at home- Ice cream in root beer (coke too).

We often tried wierd drinks at the soda fountain. One that was popular for a while was an ammonia coke- this was in the American southwest; anyone have them elsewhere?
