An island located on Lake Washington. There's a high school that other than better funding is like every other high school ever. Someday the MIHS graduates and their rivals will look back on this page and laugh and/or wonder why they ever cared so much about arbitrary rivalries. Just like I'm doing right now.
None of you are going to care about Mercer Island or its high school 4 years from now. Enjoy the ride and don't be douches to each other.
