In other words, no such thing as a "strike". Yeah, that renders the cannon pretty much useless in a race.
And that isn't even the half of it. You have to attend to understand, even with a big round they don't necessarily jump off the table, especially towards the end of the night when they are filled with lead.
When I despair, I remember that all through history the ways of truth and love have always won. There have been tyrants, and murderers, and for a time they can seem invincible, but in the end they always fall. Think of it--always.
