Packing my Running Bag

Since I am leaving Saturday and not returning until the Friday before the marathon, I thought I'd better pack my running bag for the race.
This is what I'm bringing:
Running clothes and shoes (of course)
Ipod
Body Glide
On-board nutrition (probably my cran-razz shot bloks)
Knee band
Gatorade
Timing Chip (well, I have to pick this up later)
Sunscreen (I got so burnt in the mini-marathon)
Camera (for Bill to take pics)
Facial Wipes (I always feel soooooo gross after a race)
Advil (for after, not before)
A Strechy Headband
Bobby pins
Chapstick
Brush (for afterwards...when my head gets sweaty my hair gets gross and tangly)

I know I am forgetting other things...
Can anyone think of anything else?
