It's never a bad idea to have 10-15 gallons of drinking water available.
Are you prepping, Mort?
Nah, Really it's just because I live in earthquake country. Not to say the apocalypse isn't coming, I'm just not specifically preparing for THAT.
You've put my mind at ease. But seriously, I agree that it's not a bad idea.
I've thought about it when we've had some particularly bad winter storms, but we never really lose power where I'm at. And, if I'm snowed in there's plenty of water outside and plenty of beer inside.
