Also you need to say what youre into/hobbies and things you like for people to actually give you good suggestions on where to go!
Shoulda went to boston for pax east
...Of course I should mention that. It only makes too much sense for me to think of haha
As for aquariums, I'm into freshwater nano scapes. I've got a 20 gallon stocked with boraras brigittae, microdevario kubotai and clown killifish, as well as a healthy colony of RCS. No CO2, some dry ferts and excel dosing, but that's about it. So if I buy anything, it'll be some shrimp, some easy plants or moss (god I love mosses), and/or a new nano tank.
As for the rest, I already plan on spending some time in Central Park and maybe going to the zoo. I like pubs and casual bars, but not clubs. Books, assorted and various geek and nerd stuff (videogames, collector items, etc.), writing. I like wandering around more than driving places, so the car will likely spend the week parked somewhere while I train/bus around if I end up in NYC. I'm pretty open to most anything and like the idea of adventures into the unknown. Like a friend mentioned to me that there's a bar that's also an arcade somewhere in NYC? I might try to track that down haha. Oh, and I'm a 27 year old guy, so that might help me avoid suggestions like the Princess' Playland (made-up store name, but you get the point :P).
And YES! PAX! If only I'd thought of it earlier that would have likely been a great idea for Boston haha I could make NYCC my fall nerd-out, and PAX my spring one :P
