lakes.

swimming in a lake is crazy.
you can have tons of fun, but you never know whats going on below you.
when i swam in a lake as a kid i would swim with goggles; though, i never opened my eyes.
when i did open my eyes i would quickly close them. it scared me. all you would see is what seemed like light coming from nowhere specific.
you cant just swim in a lake though. you have to have a boat to fish or a launchpod to jump on and dive into the lake. of course you have to have your king/queen of the lake, and the stupid horse flies that try to drive you out of the lake itself.
some of your best memories can be of sitting at a campfire telling old stories of how people met or of fun reunions while looking at the moon glistening in the water.
though lakes can be scary and mysterious, they can help you create your own story.
