Nesting?

I'm nearly 35 weeks now, and am feeling this weird urge to walk everywhere. Is this nesting? Is this a signal of impending baby-dom? I wonder...

In any case, I walked to work this morning, despite a nasty head cold and arctic temperatures. I fully intend to walk again later today. Normally, I'm a stay-inside kind of gal in mid-winter, with the occasional XC skiing jaunt when temps poke above 20 degrees. But today, all I want to do is walk!

FYI, I'm shooting for inauguration day for Thing 2 to enter the world. Wish me luck!
