That trip (pictured) was 3600 miles. Only tapped the gas can once, but I was pretty diligent in mapping out gas stops. The following year I wasn't so careful, didn't carry the can, and ran out of gas in Arizona. I'm sure someone here will pipe up about that any moment. I'll probably take it along from now on for any trip that leaves the Northwest. Maybe I'll buy one of those spun aluminum "tube" style gas cans rather than a "keg" style with an actual fuel line.
