First of all...because is it "Legal" doesn't mean it is right.
There are plenty of things that are legal, that aren't good for us, the environment, etc.,....or they are proven later not to be right.
We also have to understand that there are REGIONAL differences...Fish grow faster in the South, some fish are viewed differently in different areas, etc., etc., etc.
I view it as a "Regional Common Sense" issue....and yes, I understand that "Common Sense" is becoming more and more rare in our Society!lol
