Totally off-topic, but my advertisers won’t mind ;-). If you’re a fan of any of the Discovery Channel’s productions, now may be the time to stock up. They are currently having a sale on DVDs for as low as $4.99. I bought a pile of ‘em last night… I bought about 20 DVDs. I got the “America’s Road Trips” series (6 DVDs) for $13.49! Also they’ve got lots of Mythbusters episodes and collections- I owe that show for inspiring the only interest my daughters have ever expressed in physics, and it opens the door for lots of interaction with them about “how’d they do that” kinds of conversations.
