What is the great American road trip all about? Is it the National Parks? Precious time spent with the family? Those intimate human moments you stumble across when you get out there in flyover country? Or is it the food? Try the smashburger at Frosty’s and I’ll go with D – the food. They’re lining up at this Nebraska crossroads for a mouthwatering bite of a perfectly seared burger. Skinny, cooked to perfection, with the melted cheese, pickles, onion, tomato, lettuce and mayo all coming together in one blissed out, chin-wiping moment. Add a vanilla shake and I am not coming back from 1963.
