Me and my girlfriend are on our way to the US in 2 weeks for a holiday and I was thinking about asking you guys for tips on what todo / to see when we are there. We are flying to Boston, then NYC and then DC from where we fly back home. Plans so far include Baseball in Boston, Empire State in NYC and Capitol Hill in DC. We are going by bus from city to city with ether Peter Pan or Greyhound. Anyone has any hidden gems in those cities, or just a good restaurant we should try? Thanks a lot!
