Streets and Alleys
Have everyone line up in rows, so that they're kind of in a rectangle. there should be room for people to run in between people. One person is it and is chasing another. Everyone puts their hands out shoulder height and sideways. This is streets. If they put them up, same height, but front to back, this is alleys. Send the two who are chasing and being chased running through the maze of people. Start with streets. They can not cross the lines of hands. Switch as often as you want. when the two get tired pick other people-they love it!
