I forgot about those! They also have a permanat position in my lorry along with a can of WD40 spray for sticky hinges/rusty screws also very very good for getting sticky label glue off things!
Oh and I always carry ACP (I beleive it is called ACE in the US) with me in case anything goes wrong for example a breakdown. If I have to unload a horse on the side of a 70mph 3 lane motorway with 50ton trucks whistling past me then I would rather he was doped up to the eyeballs.
