Turning off water when going on Vacation

[Higgy]

I know we've had this conversation before, but it's been a while and I'm curious of what everyone thinks.

Going on vacation, do you turn the hot water tank to pilot and shut the water off to it, or just leave things alone? I've heard people say different things. Some say not to touch anything because if you do turn things off/down, that's when things go wrong and you're better off leaving things alone. Others say turn off the water and put it on pilot so that if the tank bursts while you're away, your basement doesn't flood.

Keep in mind that I'm in a very cold climate and I'll be turning down the temp in the house while I'm away.

So, what do you all do?
