Whatever you do, don't cheese out (no offense to the nacho idea). Make it something personal. It doesn't have to be expensive or cliché. Take her to a place that has significance and ask her to marry you. Very simple. Don't have a plane fly by with a banner or have a monkey with the words shaved on his back tackle her or something like that. Make it a very private special moment. Plus, that way if she says no, no one else has to see you cry
