I'm planning a surprise grill-out party for my mother and grandmother on Mother's Day, but I need to get them out the house for a few hours while we set everything up. I need my father to help with the preparations, otherwise I would have them go out together, so I thought an engaging scavenger hunt would keep them preoccupied. What do you think are some fun things to do on a scavenger hunt if you were a mom on Mother's Day?

Other info: They do not like spas/massages
