Thanks to someone who wanted to register for the Grand Tour, I found out that the phone number is out of service for some reason. It’s attached to this website, so really don’t know what’s going on. The office number is (240) 258-5250.
I have changed the number to the office so you can reach me directly. There is still plenty of time to join the Grand Tour, it runs until October 20th, so you can sign up now.
