It's not just a ban on full auto it is a ban on the discharge of any firearm within the Baltimore County no fire zone except under the stated exceptions.
I and a coworker stopped going to CS after experiencing similar issues to those above.
Parts of Baltimore County has been a part of the Greater Baltimore no fire zone for years as I was told by some LEO customers back in the 70s. It extends as far north as Mt Carmel Rd I believe.
