Yeah, Jon and I had been in touch for a few years now. I haven't had the chance to meet him in person yet, but we always try to see if we can meet up whenever he's on speaking engagements on the east coast. His knowledge of Midway is unbelievable; I haven't been able to stump him with any of my amateur questions yet
I've also emailed a few of his history buddies like Tony Tully and David Dickson also, though I don't know them as well.
