All I really need is a way to secure my back pack (I can't wear it) because I tote must os this stuff around with me anyway.
When I was a kid, my dad attached leather saddle bags and saddle rolls to all the saddles - it was a permenent thing, you rode with it or you died type of deal. They weren't very heavy really, but attached to the saddle was always matches, a hoof pick and hoof knife, a rope, a blanket - I can't remember what else but probably a ground tarp around the blanket.
