We have the "Safe 'n Sane" type booths all over town...legal in most cities, illegal in most of King County (Seattle and suburbs).
Living in Snohomish Co., just north of KING CO. all the Safe-n Sane stuff is legal, and boring.
4th of July in my neighborhood is usually (unless it rains) truly spectacular as almost everyone foregos the legal stuff and heads to the reservations for the good stuff.
Anyone need a 1/2 stick of dynamite for their mole problem? You can get 'em, here.
