Carrying the weight of the world on his shoulders

Today I thought I'd just share a picture I took at the Salt Lake City airport on Monday.  I was waiting in line and in front of me was this young boy who looked about 10-12, with this GIGANTIC pack on his back.  He didn't look uncomfortable, in fact, he barely even seemed aware of it, but I'm sure that pack was big enough to hold HIM!  When the attendant put the pack on the conveyor belt, it almost didn't fit going through the chute. 

I wonder what was in it...hopefully, something VERY light!
