At least once a quarter, right now once a month. None of it for business.
My wife and I have decided we'll have kids next year, so we're taking at least a long weekend per month away.
August - 1wk in San Diego
Sept - ? (possibly Portland, ME)
Oct - Portsmouth, NH
Nov - ? (possibly Montreal)
Dec - Italy
We love to travel, so right now is the best time to do it easily. Although others have told me the first kid is basically an accessory you bring with you on the plane, and that it's only with 2+ children that it gets really hard. We'll see, though.
