The bad thing about business trips is that you mostly only see cities at night. During day you have to work, at night you have some time to stroll around.
Last year november I got to see Boston at night, but thankfully there were some days were we could get off earlier and see stuff during daylight. Also our great colleagues over there showed us around a bit, so we got to see Harvard.
Boston is a really nice city, one of the oldest in the US. Lots of historical buildings and full of history, everybody involved in the foundation of the US did something in Boston. And you get great lobsters. I definitively need to go there on vacation some time…
