It's BYOB-- Bring Your Own Balls!

As far as I know, Mongolia is a country at peace right now, so I don't understand why I see so many soldier-types on the streets.  I've come to the conclusion that maybe they're security guards and maybe the security guards in Mongolia look extra militaristic.  I don't know.  Anyway, this game of pool on the side of the road caught my eye.  The pool table is always there, but I've never really checked to see if the balls and cues are also always there.  Maybe it's a BYOB affair?
