reply to pnh102 Why warchalk? Who cares. Scribble on my property and I will kick your a**. Like I care where WIFI is. If I am wanting to use it, guess what...chances are I am running Kismet and finding the same network you are pointing me to.
Warchalking is for kids. No one cares except the kids themselves. Years ago, we called it "tagging". Now its warchalking, whatever. Stupid then, stupid now and stupid tomorrow. Save your chalk...
