My DD wants to take a trip to NYC to see the American Girl Doll Museum. Sounds great but....what the heck do you do about car seats in NYC taxis? Part of me says not to worry about because most of the time your just barely rolling stuck in traffic, and can you picture lugging around a Regent? Do I get 2 cheap backless boosters just for the trip? But then you still have to carry those around NYC. Do taxis even let you install your seat in them?
