Survival Doesn't know Legal or Illegal!Pack a Piece with Glaser rounds in it.I know alot of the "Paper Shooters" are gonna' give me H,er Hades for this,Like those rounds are so inaccurate,etc.,etc. or you could buy a 2-shot derringer chambered for .410/.45 L.C.,A small can of WD-40 & a Bic lighter can also work.A squirt gun or bottle with Ammonia in it,will work very well!A chat with the local SLO-LEO for your area,& the address of the houses in particular,might or might not get you somewhere but, at least they will know there is a problem there before you take,Extreme measure for your safety!
