I'm old enough to remember such vehicles (if you want to call them that) in Chicago, only we called them "weenie wagons" or hot dog carts. Same copious venting of steam, large yellow umbrella shading the 'works' and rider. I'm certain ours smelled ( and tasted) much better than the one posted. Ah, I can taste it now, a good Kosher dog on a steamed bun, slathered with mustard, relish, onions, cukes and hot peppers washed down by a favorite cold beverage! Life was, still is, good!
