The current SSA regional/national rules leave the contest director with
the option of using either a finish cylinder with a specified minimum
finish height (usually 500 to 1000 ft), or a finish gate with a 50 ft
minimum height. When using a finish gate, it needs to be adjacent to the
runway, or the worm burners won't be able to make it home...
