What's in your pocket?

[Amesman]

First of all, yes, we all can see where this one could go in the wrong hands (not pointing any fingers ... ). Hoping for helpful answers, I'll pose it anyway for the curious among us (veteran and non- alike).

Other than the spare Fox 40, what do you take on the court with you?
Anything in particular for courtside?

(By the same token, anything absolutely a bad idea to bring that might not be so apparent at first, or that you've heard someone did have?)

This is gonna help a lot of newer folks.
