Have a grand time, we'll be here when you return. Trust me, we're not going to vanish from the web.
Aside from travelling in Canada, the USA and Ireland have been my only vacations that I've taken. One of these days I'd like to go back to Ireland and take a trip to Australia, Italy, or a cruise around the Mediterranean.
Anytime I go on vaction, even if I'm at home (and get rest and revamp the decor) I'm happy.
