When I need propane I always just go get it, and don't worry much in the way of details.
Tonight I found this place relatively close to my house and just enjoyed a nice spacious lot, friendly service, and expedient filling of my tank, the night before Labor Day grilling, at 7:30 at night.
For some reason it was 14 dollars and change, which is a fair amount less than usual as well.
Just way too easy. This is where I'm going from now on. It's like falling off a log.
That means easy.
