And Don't put it in the same part of your purse with anything else.
Nothing like yelling freeze with car keys dangling in front of the muzzle
As for restrictions, do not take it into schools, hosptials, and the like.
Never take it onto FEDERAL property, like post offices.
DO NOT check it in at the Court House. Even the police are not allowed to carry in my county.
Again every state is different so learn your local laws and the laws of neighboring states if you head there.
