text: help! i've been put in charge of childrens activities at our track n field end of year picnic.  ages 5 thru 11 i need to come up with some activities for the kids.  i can't think of a thing other than sack races and egg tossing.  any ideas?  we will be at a park with no access to water or electricity.  can't afford to hire people to entertain.  will buy make up to face paint..but really looking for activies. have short races for the kids. a relay race would be fun. they can handle it. have them see who can throw a ball the furthest, or create a sort of obstacle course with regular objects you may already have (walking under a high hurdle, etc.)
