A childhood belief about places

As a child, after I found out that "urine" is the "proper" word for pee, but before anyone had told me how to spell it, I was studying maps. I looked at maps of various places, including the great lakes region. When I first saw Lake Huron on a map, I thought h-u-r-o-n might be the way to spell that new word, urine, that I'd recently learned, so I really wondered about Lake Huron. I was well learned enough by then to think it extremely unlikely that there was literally a giant lake of pee there between Michigan and Ontario. But I thought the lake must have been named derogatorily by someone who perceived something inpure or unaesthetic about its waters. Even though this was a confusion on my part, it might have just given me a head start for later being aware of water pollution!
