NOTE: I'm finally back at my desk at the office today. I really enjoyed my time with my family at Universal Studios (see Facebook for some photos), and especially at The Wizarding World of Harry Potter, but I really wouldn't recommend going out of town for the first few days when you're co-hosting something as huge as the 2013 April A to Z Challenge. It's been going very well so far, of course, but I've felt bad I haven't been able to visit all of you who've been visiting me (or meeting anyone who hasn't, for that matter). But I plan to remedy all of that, now that I'm back, so I'm looking forward to reading all your posts!
