Falmingos and escalators

Thank goodness the only thing linking these two items is Sam's newfound love of them. Flamingos on escalators could be quite a mess.
Anyway, we spent a wonderful long weekend in Washington, D.C. We celebrated Papa G's birthday and Mother's Day. We visited the Building Museum and the zoo (twice). On our first trip to the zoo, we focused on gorillas and elephants, as those are two of Sam's favorite animals from his book of animal sounds "Gobble Growl Grunt." Our second visit was fish (really big ones in the Amazonia exhibit) and birds. They have a flock of flamingos that Sam could have watched all day (except that he was falling apart he was so tired) ... bright pink-orange and very noisy.
Sam rode the subway for the first time ever. The most exciting part of that adventure (and the airports) was the escalators. He's totally fascinated by them. We had some spare time in BWI yesterday, so we rode up and down the escalators a few extra times :)
Sam is getting to be a seasoned traveller. This was his fourth round-trip by air, and he's a real champ at it.
