Well, clearly if you don't know what ENS means AND you think this is a group of fine gentlemen then you ARE new around here....
Common question. ENS is short for "Eat N Shoot" (because we don't like spelling out whole words).
They are informal get-togethers that usually start at a shooting range and generally everyone brings their favorite guns, and shoot their own and each other's guns for a while, then go to a pre-arranged nearby restaurant and have a meal together. I've never been to one, but they look like fun and the last couple have come down to scheduling conflicts for me. Sometimes they center around specific types of guns (your favorite .22, or long range shoots, etc) but usually the only limits are whatever the chosen shooting range has set for their range.
There aren't really any hard and fast rules... someone will usually just decide to arrange one, post an idea of a date an place, gauge interest, often contact a range and restaurant to make sure they can accommodate an estimated number of attendees, and it just happens. Most of them are in the OKC area, just because more people in the area are willing to go to the trouble of scheduling one. There have been a couple in the Tulsa area in the last couple of years. There's a group in Lawton that I believe gets together once a week for lunch, although I don't know that they usually shoot. But they could happen anywhere that someone takes the initiative to arrange it.
Anyone who can behave themselves is welcome. I've never met either in person, but apparently druryj and surjimmy have a lot of trouble behaving themselves when they get together, and yet they still get invited. Or they crash them. I'm not sure.
