Buffalo Wild Wings - The Meeting

Well, we are less than 2 days away from EC05:The BoWash Bash, and it's starting to feel like it. Last night, the four of us gathered at Buffalo Wild Wings (yum!) to iron out a few details. We are leaving many things up in the air, but you will find a brief itinerary below, as well as a little bit of info on the four adventurers.

I am Todd, as you must know by now. My lovely wife, Sarah, is my main traveling companion. We will also be traveling with Ryan and Trevor. Ryan is a co-worker of mine at Sites USA, and Trevor is a buddy of Ryan's. You will get to know us better as we travel.

Here is our very basic itinerary:
May 21-24.........New York City
May 24-25.........Rhode Island - Newport, Providence
May 25-28.........Boston, Lexington, Concord, Salem, Plymouth
May 29-30.........Philadelphia, Valley Forge, Amish Country
May 30-31.........Gettysburg
June 1-4............Washington D.C.

Now I am asking everyone to chime in here. We have left much of our schedules open, and I want to know, from those of you who have visited these places, what you enjoyed doing. Where did you visit? What tips or tricks would you advise us travelers? What sites are simply too good to miss? Let us know!!! Click below where it says "Comments" to leave us a, well, comment.
Thanks, and this may be the last update you will get before we leave sunny Arizona!
