Happy summer to you all!  I just came back from my vacation in Virginia and I have a recommendation for you.  If you ever go near the Luray Caverns, I suggest the Garden Maze located near the cavern entrance.  The trick is to find 4 goal locations and make it out of the maze as quickly as possible.  The little gift shop is full of maze books and brain teaser activities.  I thought of you all while I was there.  Hope you are enjoying your summer!
