.... Draining it is the only way to go and I remember one cold day
when I had to drain out about a pint of water (?) from one tank. Even
taxiing around isn't good -- how long do you go before you conclude
there's no water in the tanks? Do you really want to walk back in the
cold from your plane?

What I *really* hate is when the quick-drain won't budge,
because there's water frozen above it in the sump.
