I am creating my DC bucket list

I don't know how long I'll be in DC (hopefully for a while), so I want to create my DC bucket list. Here is the start.

• Visit all major museums
• Gettysburg
• Whitewater Rafting
• Virginia Beach
• Eastern Shore
• St Mary's
• Redskins Game

That isn't a very good list. Need to research this a bit more.

Any other suggestions?
