I'm with lordtrader's ice-tray treats on this one. This was a while after I was a kid, but it should still count... The first person in the area to get an icebox was my older brother. He poured RC cola in ice trays and put tooth-picks in them. The tooth-picks were home-made, so you had to watch-out for spinters! Those things tasted great! It was really something new for us, especially considering that we lived in such a backwards place that we didn't have an icecream man or ice truck service until well after many of us had electricity and our own iceboxes.
When I was in the army, I had a chocolate malt in a bright shiny new diner in CA. Man, that was amazing. At the time, I didn't think anything could ever taste better than that. Maybe, there still isn't...
I took three of my great-nephews out in Charlotte, NC for the day last weekend. Two of them are 8, and the other one is 10. Their idea of a good treat is a place called (something like) Marble Slab Ice Cream. For three cones, it cost over $12! Frozen treats have really come a long way, and cost as much as a meal. I try not to spend more than $12 per WEEK for lunch at work. They didn't see anything wrong at all with making me put-down that much so the three of them could have ice-cream. At the current rate of advancement of frozen treats from simple frozen cola's that cost about a cent to the current $4 each foot-tall cone creations, what will people be eating for dessert 50 years from now? That's an advancement of 400 fold in price. If our ice cubes were 1" each dimension, then that would 1 cubic inch in volume. Those cones were about 12" tall with a radius of 3", then that means they're (wild-guess) 113 cubic inches in volume. The treats have grown by a factor of 113 in size. If the current rate of growth continues, treats 50 years from now will cost $1,600 and be 12,768 cubic inches (7.4 cubic feet!) in size. I love abusing statistics. Gungrabbers shouldn't have all the fun.
