Day 3 April 23

Today we will spend most of the day on the Virginia side of the Potomac River.  After breakfast, our first stop will be Arlington National Cemetery, folowed  by a quick stop at the Marine Corps Memorial.  From there, we will move on to the Pentsgon 9  11 Memorial, and then on to lunch at the Pentagon City Mall.

After lunch, we make another quick stop, this time at the Air Force Memorial.  Then we head into DC for stops at the Martin Luther King Memorial, Franklin Delano Roosevelt Memorial and finally, the Jefferson Memorial.

Now, what many of you have really looked forward to, back to the hotel to get ready for the dinner dance on the Potomac River
