Forgetting the key to the gun lock for the gun you brought.
Yes, of course they should all be on one ring. But the gun locks come with 2 keys each and there are 4 shooters of age to have possession of the keys to the guns they use most often. The numbers don't work out.
We never try taking off the locks, otherwise everyone who forgot their key expect us to do it for them. Best lesson in the world is having to go x amount of miles home to get the key they forgot in the first trip. So far it seems to work fine
Our range cat just showed up. I don't know if he's deaf (Oh yea, he is a male), or not. He's also the best food thief I've ever seen. We do warn everyone to eat their food immediately. He also loves range bags. If they leave it open he jumps in and goes to sleep.
