Went on holiday last week to fabulous New York City.  I was in full-on tourist mode and did all the big main sites! I'm still very much exhausted and slightly jet-lagged but of course I took a sketchbook with me and doodled whenever I could.  I never bothered to take any water-colours with me because my shoulder bag was already so heavy with travel junk so my sketches are definitely lacking some colour and the one main advantage to drawing in cold weather are the several pockets in your jacket you can use to hold drawing tools, so summer in New York meant no jacket so an A5 sketchbook in one hand, a brush pen and graphite stick in the other, a heavy bag on my shoulder and a big SLR camera around my neck :3
View from a window at the MOMA, you weren't even allowed to draw with pens at this museum and most of these places were incredibly overcrowded but I managed to find this sweet spot at the MOMA to draw this view because this window hid behind a wall where most people thought the exhibition ended not realizing that there was another display behind it! :)
Rodin's Adam at the Metropolitan Art Museum
I bought these brush pens in Kinokuniya, a big Japanese book/stationary by Bryant park and they're meant for Japanese/Chinese calligraphy.  I'd tried different ones before but this shop had 'testers' of all their different pens, which was how I found this one and I think I've finally found a brush pen that I love and love drawing with! I've tried every available brush pen at my local art shops but all their nibs crap-out on me after not much use.  I wish I bought more from the shop in New York so hopefully I'll be able to get them online.
Leopards at the American Natural History Museum.  Great displays of wild animals that you would rarely get to see, at least not still and in a great pose! :)
Spider Monkey at the American Natural History Museum.

People sitting outside Macy's.  Didn't do too much drawing of people but this was me experimenting with drawing figures with that brush pen really.
Spent our last day at Central Park.  It was a perfect day for it and I were so tired from the week that it meant after a little exploring around the park, I could just sit for a couple hours and draw.  Real bummed that I didn't have water-colours with me though! 
Highlights for me was definitely walking across the Brooklyn Bridge, we walked across from Brooklyn to Manhattan, just as the sun was disappearing, it was really a magical way to view the Manhattan skyline and then watching Polina Semionova dance with the American Ballet Theatre and the Metropolitan Opera House was a dream come true.
