I'm pretty conscious of protecting my identity but if you can't trust a hardworking American who owns or operates a shooting range then who can you trust? They are just trying to be accountable for who is discharging firearms on their facility and if you have ever been to a range you can probably attest to the fact that they draw a fair share of kooks and wackos at times. There are some things an evil minded person can do with your drivers license but its pretty limited. Do you same people who refuse to hand over a DL at the range refuse to hand over a credit card to be swiped by someone other than yourself? A waiter taking your card to pay the bill can write down your numbers and expiration date in a heart beat. Do a google search on card skimmers also. Unless you are physically inspecting the machine they swipe your card with, they can easily lift your credit card info in a split second. The equipment to do this is hard to detect and can be had for as little as a hundred bucks or so. This is the stuff I worry about more. I'm not too worried about some guy at the range, who probably has the same values as me, knowing my height weight and address. (All of which can be easily obtained by just about anyone) Besides, DMV is full of crooked malcontents who have all of this at their fingertips anyway.
