Sounds like you all are on the right path. Des Moines also used cattle ear tags for the World's in 2004. Proven and durable, but not unique.
I have a few hundred
plastic retractable tag clip hangers we can use - enough to last a couple years! They would also work great for keeping track of those towels that like to jump out of your bag as you walk the fairway. My wife's workplace was trashing them!
If you like I could find out how much stickers would cost to adorn the tag hangers with our logo??
