I'm sure this seemed like a perfectly good idea at the time. While the naturally animal-loving freak brigade will undoubtedly be out in force over this, this strikes me as one of those things that any of our dads would have done, given similar logistical challenges.
Ok, maybe just my dad. But then again, that's probably why I find the Vacation movies so damn amusing.
Obligatory animal disclaimer: I'm a dog lover with a Labrador Retriever and a German Shepherd, who are both large enough to probably dent my car's roof if I did something this stupid. And I still think it's funny. Hell, this even makes me like Romney just a little bit more than before; it's the first human thing I've heard about him.
