We just completed a 4 day tour of DC and the area.  We were so lucky to get John as our guide.  He is a walking encyclopedia, a wonderful man and the best guide we have ever had. I don't quite know why he isn't noted as the #1 guide.  He makes sure you see everything you want and everything else. He really takes care of his tourist and makes you feel safe. He is so FUN too.  We hope to see him again. THE BEST EVER!  Thanks John.
