Following on from the brief discussion in America's Top 100 Zoos & Aquariums, I have made a sort of plan for 4/5 separate trips through the US. Of course, there will be a problem regarding cost, but at this point I guess it is best to disregard that Anyways, here are the 5 trip plans: Day 1: Fly to New York from London Day 2: First day walking around Central Park, Guggenheim and Rockefeller Center. Day 3: Exploring piers, Intrepid Air and Space museum and Statue of Liberty. Day 4: Bronx zoo Day 5: Walk up 5th avenue to Metropolitan Museum of Art, then Times Square and Broadway? Day 6: AMNH and Central Park again before late night train to Philly. Day 7: Historical area - Congress and Independence halls. Day 8: Philadelphia zoo Day 9: Train to Washington. Walk around Capitol, Washington monument and Lincoln memorial Day 10: National zoo? Day 11: Fly back to London The question for this one I guess is to what extent are the Philadelphia and National zoos worth visiting given the extra costs of both days? If the zoo in Philly isn't worth it, then I'm sure there is enough to do there to justify a visit? Could someone who knows these cities and their zoos well give a fuzzy outline of where they sit in terms of necessity. My impression is that I would visit DC anyway, but perhaps not Philadelphia if the zoos aren't worth it. These trips are still a long way off, another 2 years until I actually start planning, while I have another such zoo trip planned for GCSEs in Europe. This one would be after A-levels and then the others would at some point in the (hopefully not too distant) future. Species I could see that I have never seen before would include: Peruvian pelican, Little penguin, Coquerel's sifaka, Nubian ibex, Tufted puffin, Bolivian gray titi, Blue-eyed black lemur, Guam rail, Guam kingfisher, Black-footed ferret, Striped skunk and many more. I will post the second trip plan in due course, which would be to Chicago and area.
