I grew up cooking on a propane grill at my parent's house. They had the grill hooked up to a line, so we never concerned ourselves with 'how low the tank was'. Or at least, I didn't. Many time I left the grill on overnight for one of my parents to notice in the morning, by accident.
When I was young, I preferred most of my food cooked by grill burnt: Hamburgers, hot dogs, steaks...I've changed my ways with most of these, but I still like my hot dogs almost annihilated on the grill for the most part. Growing up in Michigan, I never cared what season it was, I wanted to grill. If anything, I loved grilling during winter. It was probably bad practice, but I would leave as much snow on top of the grill so I could watch it melt off as the frill got hotter and hotter, it was always fun watching the snow turn to water and run down the grill, evaporating as it ran further and further down.
Growing up, I always cooked with Propane. It wasn't until I was in college and poor that I cooked with charcoal. I was able to look past my charcoal use and was able to have fun grilling for grillings sakes, but I definitely appreciate every time I use Propane now.
