i carry a small FAK with me since i work with the developmentally disabled, and it is good to be prepared (gloves, bandaids, some gauze and such) but i always take it out of my car (it's carried inside my normal work bag within a smaller bag) What i'm getting at is that i don't feel first aid supplies should be kept inside a car...the temperature can change too much (lately in FL we've had fairly cool nights and warm days)...just remeber to always grab it before leaving the house just as you would with your wallet and keys...tools and things of that nature (jumper cables etc) can be kept in the car and periodically inspected. Just a thought. Any other suggestions???
