Where the heck is Burton, WA?

I work in a Real Estate office, and have spent the majority of life in Washington, and have traveled extensively, so I’m often asked “where is” city x. Often, I actually know. Today, this one got me: Burton. I’d never heard of it until today, but it looks like a really lovely place. Vashon Island is great, though I’ve not spent anywhere near enough time there. It’s a great place to cycle. Need to add this to my places to visit list.
