Found: prescription eyeglasses at the campsite on the W end of the big island on Gillis. Not many markings, no brand or anything that I can see. They were under some dead grass near the landing area (next to a tree), only one of the temples (arms) sticking straight up. Dirty and clearly there since at least last year.
No matter what, it's never a goose chase. And next time, bring a kid along!
