Another game that we played at our family reunion a couple of week ago was a "photographic scavenger hunt". The group is divided into teams of three or four people, and each has a list of items, but the goal is not to collect the items, but instead to take a picture of the item, with one of your teammates in the picture. Each item on the list is assigned a point value, and after a pre-set time limit, each team presents their images to the judges to determine whether they satisfy the item in question. They score it totaled and the highest score wins. I think there was also 500 bonus points for being the first team to return, and maybe 250 for returning second.

I managed to find the list of items and their respective point values because the item list was in several of the photos I took. Some of the high-point items were there largely as jokes, since we were unlikely to find them in the park area within walking distance of the campground. Like an actual robot.
