Nice post Charlie and glad you made it out ok. This is great reminder of how easily we can find ourselves in a bad situation.
I like you list and for I would add:
GPS
Lighter (Nice to use over matches)
Wax Tipped Matches (I see you had matches but I dip mine in melted candle wax to water proof them)
Radio (I always carry one that picks up weather reports and I figure I may be able to call for help on different frequencies since lots of people carry them now days)
Small Baggy of Treats (In a survival situation some tootsie rolls, small salt and pepper packets to choke down what ever you find to eat, and some water flavoring containing electrolytes, some ibuprofen, and calcium tablets for heartburn, and some pills for diarrhea can go along ways. This one isn't critical bad I think it can make a bad situation a little better and doesn't take up a lot of space.)
