Forgetting to throw it before the storm comes!

The best place for a switch (or physical disconnect) is before the feedline
enters your shack, with the shortest possible connection to ground.  Which
makes it inconvenient to toggle.  Putting the switch inside the shack adds

For discharging static before it builds up to dangerous levels, a switch
inside probably works.  But for anything approaching a direct hit (keeping
in mind that nothing can save you from an actual direct hit), putting the
switch inside brings the energy from the lightning into your house, which
could ruin your day.
