The hotel I used to work in (1989 to 1998) had an indoor pool and we sold disposable paper swimwear. Guests would buy and use them. Just did a Google search, disposable swimwear is still being manufactured and sold today. Until I read your post, I hadn't thought about it in years.
I grew up in along the Humptulips River. I knew it would make the list ;^). I get a kick out of telling people where I grew up and seeing the look on their faces and saying "Hump what?". It's actually an Indian word meaning hard to pole, as in using a pole to navigate a canoe on the Humptulips River.
