I miss the good old days when you could have cap gun battles in the streets or nearby parks and not worry about getting shot.
Cops would even drive by and not give a flying fuck.
Hell, one of my childhood friend's father's was principal at a middle school in a nearby town, late at night we all drove up and had the entire school to ourselves. (Epic gun battle ensued)
At school we could bring cap guns and bb guns for stage productions or in-class "skits", without everyone yelling bloody murder and freaking out.
Albeit this was in rural Atlantic Canada, not Calgary...our backyards are many acres, as big as some airsoft fields.
That said, times have changed. Call the cops.
