Nice vacations are key to my equilibrium. Those are the moments that remain stored in your memory, for all your life. I think also that vacation is fundamental for the long term health of a person, and when I come back from a trip, I am twice as productive at work (trying to explain that to my manager ...!!!!).
Here are some nice places I visited recently:
Cabo San Lucas, 1998
Yellowstone, 1999 (2 minutes show, 2.5MB file, don't do it at 56KB !!!!)
