I've been giving some thought to our GHB's in particular, but BOB's as well. Something I've been considering adding to them is an amount of cash $5, 10, & 20 bills, plus some silver dimes, quarters, & halves. My thinking being I'm stuck at work or somewhere and end up walking home, there is a chance I may need some funds for an item, passage thru an area, boat ride across the lake, any number of things. Cash as long as it's still in use, silver if cash should become useless or worthless.

What's everyone's ideas on this? Anyone else already have this in practice? What amounts seem prudent?
