Mutter Museum, Philadelphia
SEE THE MUTTER MUSEUM! It is something that most tourists don't go to because they've never heard of it! Also, you must go to Pat's Steaks in South Philly for a real cheesesteak -- trust me, those Steak 'Um sandwiches don't pass for the real thing! Other things that are a don't miss: The Mummers Parade (on New Years Day), the Mummers Museum (4th & Washington), Italian Market, the many ethnic festivals during the Summer on Penn's Landing...
Fondest memory: Anytime I go away from Philly, I constantly miss the food.
