Do I have to buy a Boomer Button for my kids too?

Yes.  All children over the age of 1 year are required to have a Boomer Button to be admitted to the festival and to participate in activities.  Children under the age of 1 year are not required to have a Boomer Button to gain admission to the festival but without a Boomer Button they will not be allowed to participate in activities such as face painting, balloon artists, petting zoo etx.
