In the Rules :
1. You must be at least 17 years old at the point this competition closes and resident in the US. Proof of age will be required if you are the winner.
2. If you are under 18 at the time of travel, the guest who accompanies you must be a legal guardian.
I dont think an 11 year old would fit in walking around a high scool :)
Dont worry though cuz i am too young to enter too!!!!
