Yep, his son, IIRC. If you go to the link, you'll see the article is really from the Firearms Coalition, which is Knox's "outfit", now run by his wife Jay and sons Jeff and Chris after his passing January 17th.

I also should have included Neal and Jay's daughters Shan and Stacey as well as their sons Chris and Jeff.
Speaking of shooting. Someone is shooting outside (11:41PM here) but not some little popgun like a .50 BMG. Sounds like either tank or artillery fire. Since I'm only a few miles from some of the ranges at Ft. Hood, it could be either and my Air Force ear isn't yet tuned to Army well enough to tell the difference.
Kewl......Thanks !
