I would also include.... a wallet with photos, an ID or Driver's license, some cash, a debit card with a small amount of money on it. A watch.
if I had to skip out in a hurry... i may not have these things on me. If detained in a camp... and escape, these things would probably have been taken away... with clean clothes... looking more like a jogger.. don't forget a bottle of water and a head band... maybe a cheap ipod... with a wallet and watch, they may stop you but let you go.
Because of earthquakes, my kids and I buried a rubber maid tote not far from their school. It contained a BOB so if the school went into lock down... they could get out in the confusion and head for home through a canyon and wash.
We sealed the lid with silicone sealant to keep the water out. everything in it was old and expendable.
