Champaign Canoeing is located in Ossining, NY, (35 north of NYC).
If you're looking to spend a fortune and dislike trendy hotels, stay at the Carlyle.
An excellent independent bookstore in Nolita.
The restaurant next door is always crowded, but be sure to stop in for a pastry (the tarts are always heavenly) or a croissant and cafe au lait.
