We went into the Smithsonian Castle just to see what it held. Then we crossed the Mall and spent a few hours in the Natural History Museum. I love old museums which have been upgraded as they're all touchy-feely. Many times when travelling in Europe we stopped off at this type of museum but seldom found any completely free.
Then, we headed for Dupont Square just to end up grabbing a Subway sandwich. A special offer means that all foot-longs are $5.00 and one did fine.
We got back on a Metro line to go to the Smithsonian Zoo over in Virginia. Until the end of this month the exhibitions all close at 4:30 and the premises at 5:00. Therefore, we ended up missing the "Big Cats" but saw most else. They are making a vast improvement for housing the Asian elephants. Again, it was a nice zoo considering it was also free. We got back to the hotel room after 6 o'clock.
We'll probably just get Chinese takeout and eat dinner in the room. Tomorrow, we've got to continue the streak at Air and Space Museum first off tomorrow. This is a slow paced vacation but it's fun seeing all the families and school groups out probably because they're on school break. I like being a tourist when others are doing the same.
