How about glow-in-the-dark shrink tubing? Glows at night and is neon pink in the day. Or maybe glow -in-the-dark lanyards?

I guess a lot of people lose their stakes. I took the family camping and brought the metal detector. The kids got a kick out of finding all the loose change people drop, but you should have seen our haul of tent stakes! About 40 of them in just 4 camp sites. This is just one more reason to love hammocks.
