have to support the economy by buying more oil to heat up your home, either that or you will freeze to death in the winter. my mom asked me one time if we could just use candles to keep ourselves warm...boy, i wish. had to buy few gallons of diesel for my friend's house to keep the heater running while he is away. why? don't want all the pipes to freeze and burst, and create bigger and extensive damage in the house. and yes, the gas tank is outside right in the middle of the yard.
