We have a "commercially made" human First Aid kit that we keep in the trailer. My husband got it through his work. It has all the essentials like Band-Aids, First Aid cream, wraps, etc. We have also put other "horse things" in it, like long cuff gloves, paste Bute, bigger bandages, etc. My brush bag has Vet Wrap, scissors, and the horse thermometer (DON'T put that in your human kit and risk someone using it on a human especially after it has been used on a horse!
) We carry duct tape in the trailer, too. Depending on where we go and what horses we are taking, I might throw a bottle of Banamine in the cooler. So all my First Aid stuff isn't all in the same spot, but again, I don't like to carry more than absolutely necessary, and when we will more than likely use the Vet Wrap to wrap tails, I don't want to pack more in some other spot. BUT, I know where everything is in the trailer, too.
We have a toiletry bag that we call the "Ditty bag" (I don't know why, it's just what Chad called it.) Initially when we started designing the trailer, I wanted the small cabinet to have shelves and racks that all the Ditty bag contents could be located in when we stay in the trailer. But before we got that done, it occurred to me that having the stuff in one bag makes it easy to grab and go when you get home from the show in the middle of the night, and all you want to do is get your contacts out, brush your teeth, and go to bed in your own bed! So the whole Ditty bag fits in the small cabinet. The First Aid kit used to be in cabinet, but since we don't use it very much, it got moved to a shelf over one of the windows in the gooseneck.
Good suggestions about using Ziplock bags!
