You don't have to spend a fortune on swag that isn't junk. Right now in my bag, I have:
Camp towels (the kind that are compressed to the size of dollar coins)
Mini bungee cords
Salt & pepper shaker lids that fit on film cannisters
Carbiners
Utility straps (the kind that would go around sleeping bags)
Sewing kits
Folding scissors
Safety whistles
Mosquito net hats
Bear bells
Flexible flashlights
First Aid kits
I didn't spend more than $2.50 for any of it. If I 'regift' anything, I include something new from my list as well.
