Everything looks good, but I change Boston from a Market to an Aqueduct. Rather have the city continue to grow first and then build the marketplace. Change Seattle to an Aqueduct as well.
IBT-
Washington: Longbow -> Worker
1) 360AD
Settler founds St. Louis
Our core cities have very little defense. I'm moving 2 horsemen from the north to DC to cover our core towns. The longbows and other slower units will head north to our eventual war zone.
Greece has wines, which we can get for horses. But they also have iron and I do not want to let them build knights because we will be attacking them eventually.
IBT-
Washington: Worker->Temple
Boston: Aqueduct->Market
Romans build Sun Tzu's in Antium.
2) 370AD
IBT-
Japanese build Knight's Templar in Kyoto.
3) 380AD
Up science to 20%; Printing Press now in 29 (over 46).
5) 400AD
Trade Scandinavia Invention for Monarchy + WM (they were the only one w/o the tech).
Trade England our WM for WM + 1g.
Trade Japan WM for WM.
Trade Rome our WM + 1g for WM.
Trade China our WM for WM + 1g.
Trade Greece our WM for WM + 2g.
IBT-
Washington: Temple->Cathedral
Rome builds Sistine Chapel. They are getting big.
6) 410AD
Education and Gunpowder are now known by 3 other civs.
Washington DC is now at 20 shields per turn.
We can get Gunpowder from Greece for almost everything we have... 210g + 18gpt + horses... not what I want to do.
Disperse a barb camp near Tsingtao.
IBT-
New York: Market->Temple
Shanghai: Trebuchet->Settler

Trade Scandinavia our WM for WM + 19g
Trade Greece WM for WM
Trade China WM + 9g for WM
Trade Rome WM for WM
Trade Japan WM for WM + 2g
I went for more infrastructure, but I'm regretting that. We need to take over our continent as quickly as possible in order to keep up with the tech pace. Keep researching Printing Press as hard as possible. With luck we'll get a monopoly on it and pick up the other techs we need.
Fighting Greece may be tough, especially if they have Saltpeter. Once DC gets its cathedral finished 2-turn LBs are possible at 20spt. There is a worker mining near DC. When it finishes, we can shuffle some citizens: move the mined BG that DC is working to the newly mined plains so Houston can pick up the BG. This keeps DC at 20spt and allows Houston more room to grow.
We need a lot of things, and I probably should have popped off more workers than I did.
Up north we can fit in a town 3SE of Beijing. Also, I have been converting those towns into research farms, irrigating everything and using excess food to hire scientists. We need all the beakers we can get to keep up with other civs.
The worker mining a mountain in the south feels silly now; it may be better to cancel what he is doing as it won't be of any use until Seattle gets irrigation. Atlanta needs its goats mined now that it has expanded boarders.
