Hmmm...I probably hit right around 28 gallons actually.
A few more miles (maybe 1200) IF we're talking actual distances walked, rather than including just around the house.
No idea what that might work out to, but I'm assuming it must - because I highly doubt that most people walk anywhere near as much to locations as I do. :/
Indeed, for beer-fueled walking (to and from the bar) I only get around 500 miles per year. I use other fluids for other walks (usually tea -
and my milage there would be bloody terrible: I probably drink close to 300 gallons of tea a year!)
