ok, so the american icon tour continues tomorrow with the mall and assorted smithsonian museums, and monuments........we have about 10-12 hours of total downtown time..........and no agenda other than to see everything.........scw and i have been to downtown dc many times.......but there is always something new to see at american history or natural history..or the national gallery........i like the indoor waterfall in the national gallery cafeteria designed by i m pei.........of course, i am worried to fly during a time of high alert...........but then, being mean, i will probably head-butt a would-be terrorist for attempting to ruin my 2 days off........i am also looking forward to seeing roseanne and nick, my in-laws........
