I've done 1, and only 1 of these. The hunt was supposedly broken up by age group. My daughter would have been in the youngest. (IIRC, she was about 3).
Parents were directing their older kids into "our" zone. My baby girl was competing with kids with starter mustaches for some G-D plastic eggs containing 2-4 jellybeans.
Needless to say, she got skunked until some of the less dooshy parents took notice and re-hid their kids' eggs so she could find them.
I never came so close to going Old Testament on some folks. (Get it? Old Testament? Easter)
I'm not bitter.
