Very cool we'll have Josh in the gaggle!
As I mentioned over in the Gotha thread, I hope we get a chance to do this on a couple different mornings. Or every morning!
It ensures people who might not be able to make the entire event (Wed-Fri myself) are able to join in, and it creates an opportunity for people who get inspired in the morning to build something during the day and join patrol the following morning.
If the extra patrols are strictly unofficial and not on the formal schedule with Josh, I think that's fine too. I think it will be quite entertaining seeing the scarred and taped up remains of the barons and brits on the second or third dawn patrol after a couple days of combat too.
