When I run, I keep my phone in a FlipBelt, an elastic waistband with pockets. To protect it from sweat, I put it in a small plastic bag. Today, after finishing my run, I walked home and got my phone from the Belt, and suddenly a lot of ducks came swimming and walking towards me! Apparently the rustling of the plastic bag attracted them, I guess a lot of people feed them bread (from plastic bags) at that spot. It was funny.
