After reading through the posts I have a thought I'd like to toss out for the discussion that I'm not sure anyone may have had. As everyone knows, homeland security events have changed the way business is done in this country in a variety of ways. Obviously, gun purchases are regulated (at least those that are made through shops) via background checks. (And no, I'm not a gun control fanatic but I agree with having background checks done.) The issuing of commercial drivers licenses are tightly controlled through the use of background checks, especially if driving hazardous or flammable materials. Heck, where I live they even check your drivers license to buy some cold medications now due to the possibility they may be used to manufacture meth & other nasty drugs. (I don't really agree with this one either & think it's a bit overboard but it is what it is.) Furthermore, we are all aware of the potential consequences if someone drops or damages a scuba cylinder, especially if it is full. If you need reminded, please check this week's St. Petersburg Times about the diver who was killed & the damage done when his tank exploded. With all of this said, what do you think about having a background check for the purchase or fill of tanks is someone does not have a valid c-card to show at the time of purchase & if you do have a c-card, making it part of process of getting one in the first place?
It's just something to mull over & I'm sorry if I started an off-thread topic on something that many people feel so passionate about on both sides of the fence.
