thanks everyone.
yes, we were dead tired. We were up for almost 2.5 days with near 0 sleep. I took a few naps along the way, but that was it. And yes, I did play my DS, mostly while sitting around waiting for things to happen. I even held Leif while playing, which isn't too hard to do. He has officially been exposed to Mario & Luigi, so we'll see if he likes RPGs when he grows up
