We are having a scavenger hunt this year for so I have been doing a lot of research. Here are some links I found and if you need some more specifics -- if you can give me a little more information about what kind of hunt you are looking for and a little more details on the "area" you are using. Are they driving around town to houses, stores and such or remaining in a neighborhood or on foot.
I would suggest a combination scavenger hunt and video/photo hunt for that age group. We are having the kids hunt for the items on the list, as well as, have do a photo/video hunt where they need to have all of someone in their group in a picture or video "doing" something to get points.
Example:
a team member posing with a scarecrow, bale of straw, or shock of corn
get a policeman to put on a fright wig
a team member standing next to the largest pumpkin you can find - vote on a winner at the viewing after the hunt!
a stranger acting like Dracula and saying, "I vant to suck your blood"
a team member standing next to a tombstone
the team singing and dancing the Monster Mash in a restaurant
have the team become mummies: they must go to a store, purchase toilet paper, wrap one another like mummies, and leave the store that way
get a stranger to spell "Frankenstein" forward and backwards
Another suggestion is to have them all in costume so it is obvious that they are doing a scavenger hunt and not out to make trouble. They can name their teams after horror movies or horror monsters.
Here is a list I found on line -- These items should be found and never stolen. Get permission if you need an item from somebody's yard, you don't need to be adding handcuffs to the list.
