nightowl, one of your points is being addressed with the "Trigger Trash" campaign - you've seen the billboards on I-10.
I wear BDU pants sometimes - very comfortable, and the extra pockets come in handy. I wear Blackhack boots, lightweight, comfortable, good for shopping or hunting, and I hate buying lots of shoes/boots - I leave that to my wife. I also wear big t-shirts in summer time, better to hide the full size pistol I carry concealed, legally since 1994.
I've been to the range when Tommy Tactical and his five buddies show up, and make a point of trying to impress everyone with the expensive gear they are hauling. I find that sometimes I can outshoot them with my bolt action iron sighted carbine. Sometimes they ARE what they look like, and really can shoot. Others are just having fun. Whoopee. As long as they are SAFE about it, I don't care how they dress - just BE dressed...some of them would look quite bad in the nude...*shudder*...
I had an egregious safety violation in front of me when I was working at Jensen's West indoor range, by an FBI agent in a suit. I threw him off the range.
As for alcohol and shooting, I agree that the two do NOT mix, even though others disagree. It's the same as booze and cars, two absolutely legal products that should not be mixed together, no matter how well the person "can handle it". That's my opinion, and the opinion of many professionals who carry guns for a living. I would never pack a few "cold ones' on a hunt, unless we're talking sodas. Too heavy for this fat old man to haul around.
To reiterate and agree with the others, I don't care how you look, how you dress, just how safe you are. If you are unsafe, I will leave. Period.
