It sounds like a super-cool time!
I hate to admit it, but all we have right now is a shotgun. That may not be the case by then, though. We’ll see.
Irrelevant.
You could show up with nothing and still shoot all day, picking from
20 or 30 different pistols and probably a larger number of rifles.
It's like a gun show where you actually get to shoot whatever appeals to you.
More than once I've gotten home with a couple pieces what didn't even get uncased.
I can attest to the truth of this.
I brought four rifles and only uncased two.
And one of my handguns stayed in the trunk as well.
So if someone was to appear empty handed so to speak,
I could help out in such a situation.
I have a feeling others could as well.
In fact the mood is one of eagerness to share the
experience of your nicer and more unusual pieces
with the friends you meet there.
