I'll fly to the U.S.A at teh end of next week, and will spend one week in Florida.
On my way back home, I'll be landing in JFK airport, and will leave 6 hours later from Newark.

Therefore, I hope I'll have 3 hours to spend in NYC.

What would be realistic to plan in these hours ? This will be on a Saturday, so I guess photoshopping is not an option (or maybe the Crumpler show room ?)

Cheers !
