It is not paranoid to be careful...
I used to shoot alone often back east @ an indoor range and @ a Sportsman's Club.
No range officers on duty unless there was a special even going on.
I did not leave my firearms unattended even if I was 'alone' or had another person with me. If the person with me was someone that I KNEW like my late husband or a best friend or super close GUN friends... OK... we watched each others GEAR.
IF there was another person there, always a man or men, rarely any women there at either place when I shot... I took out what I was shooting and used it. I kept one firearm loaded - holstered on me and when I LEFT the indoor or outdoor range - I had to UNLOAD the LAST Self Defense Firearm because it was a NO CCW deal in that RINO lying governor state even though he made false promises to get elected. UGH. When I shoot totally ALONE and the range is empty or NO one is there... I do the same deal.
Out here... I mainly go to the range with my husband and/or with our gun friends.
We follow the same deal. At events: MOST of the small group of out of state friends and IN state friends conceal and open carry. EVERYONE is packing plus what we already are shooting. Guns are all lined up and each guy has his stuff OUT. Ammo, brass because most reload, gun gear, you name it! Sometimes there are so many firearms... we put things out... put them away... bring more out! (Speaking of militias! Dang good shooters too! Ha ha!) We shoot each others firearms IF it is something that interests us. These guys come from several professions, most are former military, some are corporate guys, some are forest rangers, some in medicine, some in their own security business and detectives, some are railroad people and some are retired as I am. You name it and it is a VERY super close group of people.
MOST of the time back east... I shot ALONE. I went alone when I was safe enough to shoot alone. Once in awhile... my late husband went with me if he was able to go, my police and/or military friends, a gun/political buddy or two and I even took some ladies to the range too. Newbies.
You never know and I would trust most people but there are some in any sport that I would be cautious around. Not because of THEFT but because I don't like them SAFETY WISE or just do NOT care for them as PEOPLE.
Some man on a board that I recently quit said/wrote to me that paranoia runs DEEP. It was about a computer security issue on THAT board that I dared question among other things. Well, if he could see me now... I would say that STUPIDITY runs even DEEPER and it is better to be SAFE than SORRY whether it comes to firearms or ANY other OBJECT or TOOL that one is using. That goes for anything - anywhere!
As they say... watch your six and shoot straight!
