I like to think it starts with the planning since we are down to about 1 trip a year. It's the setting the countdown clock, the lurking on this board and soaking up all the info on what is new in the last year, the places I have missed (just found out there is a Miller's Ale house there!) Reading the yummy trip reports that everyone so nicely shares. It's the laying around our pool all summer so I can get tan enough not to fry in the August Vegas sun. And all the boat drinks that goes along with pool time. Mostly though it's my brother in law arriving at the house to pick us up for the airport with a bottle of champagne and a rebel yell that "vacation has started".
