llforrelaxin......you better sell a LOT of gas if that's your only income stream. Can it be done, I supose so, but I've never seen it. You might be able to make a weeks pay, but not a living. By a living I mean raise a family, send the kids off to college, and own your own home.
My dad did well, a solid middle-class living, but he worked 60 to 80 hours a week all his life. Plowed snow around the clock in storms. He put in a lot of hard work. Most people in that business are not getting rich off a few cents per gallon of gas.
