I was distracted the moment you mentioned that you had a 60 mile bus ride. Holy cow!
If it makes you feel any better...
A few years ago I and a couple of employees were hanging out around the front door of our office, end unit of a business strip center, non emergency ambulance transport company, just after dusk on a hot summer day.
Car rolls down the drive in front of out lot real slow, makes the circle at the end, rolls back. This puts me in orange alert. Just as they get past our door, a barrel comes out of the back window and we hear a quiet (suppressed) semiauto firing. I instinctively draw my strong side OWB weapon and take cover against the slanted wall that leads into the door. Or did I? I have my work pager in my hand, in the ready position! Oops!
Turns out they were firing a semiauto BB gun at a neighboring business' store front and vehicles.
