What do you keep in your bag?

[UNIgiantslayers]

I apologize if this has been discussed or is a weird question. I had a long drive after our game last night, and I was thinking of all the times I've learned of a new thing that needs to be in my bag. Usually I realize it should be in there when I don't have it and need it (i.e. baby powder, deodorant, rule book, extra whistle, etc.) I'm just curious if any of you have anything in your bag that you recommend for young officials to make sure they have. Thanks, in advance, for your input.

FYI, here's my inventory:
Extra whistle
Chap stick
Towel
Rule book
Baby powder
Deodorant
Hand sanitizer (I'm a germaphobe)
Water bottle
Watch (for the table if they don't have something for timeouts/DQ sub time)
