I always keep a handful of loaner or giveaway discs in my truck. I've got a couple DX Rocs, Aviars, Sharks, Leopards, and some other beginner friendly discs. You never know who you might run into or what kind of situation can occur so I like to be prepared. I have to restock every so often because these discs always find their way into the hands of curious kids or beginners who don't understand why their max weight Ape won't fly very well.
