We have a gate with a code. But it’s a universal code, so they cannot tie it to me as an individual. I had to provide my information when I joined years ago, but I don’t have to do it when I go. I will admit that when I go, there is often no one else there.
And this is in MA.
I know at some indoor ranges they are much more strict. But those are in the city and they need to avoid the local gangs from “training” there.
I don't know if the gate key card for my gun club is tied to me. Yeah, and like you, I'm usually there during the week and frequently alone. But I always sign in because those are rules I agreed to.
I would think any insurance policy would want records to be kept of who was there.
