I too, have carried quarters, dimes, & nickels in my BoB for years & years. I have found myself marooned more than once in BFE but in the vicinity of pay phones and vending machines, which made the waiting for retrival much easier on me.

I will continue this habit!!

I like the old cell phone idea,,Thanks!!
