I saw this question on a boating forum:

(For us northern boaters)

With the price of gasoline skyrocketing will you top off the gas tank before
you put the boat to bed for the winter or hold off in hopes gas pricing will
come down by Spring?

Topping off is the gas tank is a necessity for some folks....others feel
differently and that debate goes on. So let's keep that debate out of this
thread if we can.
