Thanks for the reply.
By the way, I know that Moma(NY) is free of admission on Friday 4pm-8pm.
However, I went there at 4pm in January and there were full of people..
I wanna ask whether I need to make reservation to admit on usual day and on the day of free admission?
Thanksssssssssssss! =]

Nothing to see in Buffalo, except shopping. Closest major airport to Niagara Falls is Buffalo.

Boston, OK 啦。　到各大學府一游，河邊影相，　Faneuil Hall Market, shopping, 食海鮮

Buffalo 真係無乜野睇，主要係去 Niagara Falls 要經過佢。
Niagaras fall Int'l Airport 係比包機用，普通航班係停 BUF。
我去美國一定自駕遊，所以搭車住 hostel 果ｄ幫唔到你...

Ha~ Something about Moma of NY asked above..^^"
