Welcome to the You Don't Know Yosemite game! OK, really it's more like a quiz than a game. But who wants to take a quiz? Not me. Calling it a quiz would be bad marketing. So it's a game.
Like any good trivia game, You Don't Know Yosemite is out to get you. It starts easy and gets harder as you go. It will grudgingly accept you when you're right and taunt you mercilessly when you're wrong. It will offer you hints and then deduct points if you're foolish enough to accept them. It has no redeeming value.
Anyone can claim all that, of course, but You Don't Know Yosemite has one huge advantage over all other trivia games: you're already on this page. So you might as well try it.
