A neighbor! I'm in Rancho Santa Margarita, just east of Mission Viejo.
So, at least we know there will be 8 of us on the trip! I wish my husband could go, but he just started a new job and can't get the time off. We're actually flying the 5th, to give us an extra day in Pennsylvania. At this time, I am thinking we're going to do a day at Hershey park, but that could change easily into a day at Gettysburg. My son Dylan is a huge history buff, and I can't wait for him to see all this trip has to offer. We used to live in Pennsylvania when I was his age, so it will be neat to go back with my parents.
Did you get your flights already? I found a good deal for us on American flying out of LAX.
