Halloween 2017: socially distanced halloween scavenger hunt/amazing race

looking for fun, creative ideas for an outdoor scavenger hunt for college kids. i have a few outdoor locations where stations can be set up & i was thinking of have a few small groups (three or four in each) & have them dress up & run around campus & play games/challenges at each station. i am struggling to think of fun games that are halloween related & covid friendly but i figured i should ask all of you for help!
