I work for the official photographer at a very big sports complex near Minneapolis, MN. The company employs between 3 and 6 photographers at a given event with at least 2 people manning a set of 5 computers.
I brought my usual stuff this morning (745 AM) to the rink:
In a bag: Canon 20D, 24-70 2.8, 70-200 2.8, 580EX, Kenko telecon and batteries
On my shoulder: Canon Mark II and 300 2.8
The idea is that each photographer will shoot two rinks at a time, then return their memory cards to a download person, take a brief break depending on how long till the next game, then go again. Today in particular was the playoff day, so we didn't have much time as the games were close together.
I put my camera bag near the end of our table, with the rest of the camera bags- except mine was the closest to the outside. I only carry the rest of my equipment when I have a team photo to do - otherwise I don't have a need for it - just added weight.
I returned at 1230 to grab my lunch to discover that the bag was gone. All the camera bags (everyone else's) were still there, but mine wasn't. We searched our little area for it, under the table curtains and in boxes, and also called all photographers to make sure no one "borrowed" it without telling, though everyone there has a better primary camera than a 20D anyway.
Security is notified. Police are called, incident reports are filed. Everyone is apologetic, knowing that there's really nothing we can do. Anyone who stole it would probably not be stupid enough to use it and would prefer to take the very easy getaway, since our sales people are distracted with customers and only a flight of stairs keeps them from the doors of the crowded event.
I leave, told that I should get my serial numbers and call the police right away to add said numbers to a database for pawn shops.
As I turn out of the facility, something is really nagging me. "Rink 6 Rink 6 Rink 6" I keep thinking.
I drive back, compelled by the voices in my head.
There's the bag, with everything in it, BEHIND A TRASH CAN.
I pick it up, calmly explain to security and the rest of the photo staff what just happened, and go home.
I know for a fact that I didn't remove the bag from behind the table as I had no reason to - weird, huh?
Anywho, just saying that I almost had 2600 dollars stolen from me today. Only take what you need. You might not have voices, too.
And if you don't believe me that I didn't leave the bag there myself, then what will you believe? 
EDIT:
My theories: Tons of kids walk behind our booth not realizing that they shouldn't. One could have taken mine, being the smallest bag.
Or maybe someone's crack was THAT expensive and they found something else even more expensive to steal.
