You’re such a good dude Prox. This like all things will have varying amounts of logic, statistics, anecdotes and most importantly...opinion! Like all things in life, you’ll never get all sides to agree! Anything is better than nothing and just being mentally prepared in your own awareness of your surroundings, recognizing and acknowledging the potential for threats and being willing to advance on those threats is so much more important then having your head buried in the sand. I’m sorry that you and your wife were so rudely awoken but the fact is that you were and you’re now both better equipped. What and how you choose to defend your castle is a personal choice and I have NO doubts you and the Mrs will make the best choice for YOUR home and YOUR comfort level!
(Side note...you saw what Salamacca did with a cast iron skillet full of hot grease on BCS, right?

You rock brother
