well, I guess changing wife is not an option, right ?!? <img src="/images/graemlins/grin.gif" alt="" />
And her BIG purse is allready full ....

then an ankle pouch might be the solution.
I no longer use one for EDC, but on such an occasion, it's perfect.
(IIRC, there was a thread about those pouches, a few months ago...)
