Wow, thanks folks! Peace, that link was most useful. But I am enjoying just as much (and more) tasting your own memories of such places.

I will return later today (from work) with my own "frappe" story/recipe. Meanwhile, I hit the road with the following facetious question in mind - no need to answer it:

Did they hold competitions for soda jerks, and what were they called? ;-)

Really, thank you all so much!
