Carey and I collect mugs from the places we've traveled together. It all started in New York, sort of by fluke, since we were simply looking for a souvenir that wouldn't just sit around and collect dust. Then we added a mug from Chicago, Busch Gardens (Florida) and Toronto. We limit ourselves to 1 per place, though, otherwise we'd have 2 from Chicago and 4 from Florida (we're missing Dominican Republic though, where we went for our honeymoon - guess we need to go back!). I find that they're a great keepsake, since we get lots of use out of them (we only use our "matching" mugs when we have company) and I love to think back to our vacations while sipping my morning coffee, or while enjoying some hot chocolate on a cold day.
This week we added this baby to the collection. Can't wait to try it out!
