. You could have it be a treasure hunt of all the places around your city that are important to you, or a treasure hunt that plays on some of his hobbies. There's no wrong way to do a treasure hunt (unless it's too hard and he can't complete it). He'll be having a great time and be in fun mood for the last clue (the proposal). Lots of people like a good proposal that has to do with food (as long as he doesn't end up eating the proposal by accident!). There are lots of ways to use food to make a fun marriage proposal.  There are ways to have personalized fortune cookies made. You could have one made that says 'Will you marry me?' and make sure it gets mixed in when you get take-out (or if you make some lovely Chinese food). Hide a note and symbolic engagement gift (not necessarily a ring) amid a box of delicacies and give them to him. Again, make sure he doesn't eat the note or the gift by mistake. Around Halloween go to the pumpkin patch and challenge your guy to a pumpkin carving contest. While he's diverted, carve 'will you marry me?' on your pumpkin and present it to him when you're both finished carving. You'll probably win the contest then. Obviously, this one isn't for everyone, but if you and your guy are super into extreme sports, it's a great way to pop the question. You'll probably need the assistance of your friends or instructors, so make sure they don't give away the game beforehand!  Go skydiving with your guy and have your friends spread out a sign below the two of you that asks him to marry you. Go scuba diving and have a waterproof sign already planted down on the ocean floor for your guy to find with you as you're swimming around down there together.
