1 - Send your girlfriend on a treasure hunt. Start with a clue at home; then send her on a tour of your favorite spots all over town. When she gets to the last hint, the prize should be you on one knee.
2 - For a simple surprise, after she goes to bed, go to her jewelry box and replace her everyday ring with the engagement ring. She'll be completely shocked in the morning when she goes to put on her regular ring.
3- Upload a video of your proposal to YouTube (tell her you have a hysterical home movie to show her).
4 - Make your own message in a bottle. On the night before a beach day you've planned, write a love poem on a piece of parchment paper, roll it into an antique bottle with a cork and bury it in a well-marked spot in the sand near your towels. Be sure you "find" the bottle as you dig together -- and have the ring at the ready.
5 - Tell your girlfriend you want to make a time capsule together to bury and dig up years into the future. As you're gathering the items, say it wouldn't be complete without a picture of the moment you two got engaged! Have a camera ready to take that shot right after you present her with the ring.
