More than one drink means I carry less than one gun. PEPPER SPRAY is usually a good alternative carry piece when you are in a can't/won't carry, less than peaceful, less than lethal situation.
In MA, you may not carry under the influence but there is no prohibition on carry in bars, clubs, etc. I used to work at one in Boston and I would leave at 2:30 AM alone with substantial cash tips. My G17 was always with me when I left, and it either stayed with me the whole shift or it was locked in my locker in the employee room.
