I have one of those storage containers that I take with me everywhere. It has everything from corona oinntment, wraps, rubbing alch, sutures (just in case it is a complete emergency and we are on the road), lots of cotton, electrolyte pastes, bute, $100 cash, yellow spray, a fly mask in case it is an eye problem, anti-hist. I could go on and on.
Im a paranoid personality while Im traveling with horses, so I if I cant take the whole barn, I load up an all the first aid I can stick in that box.
