EVERYONE is required to sign the liability waiver or have a waiver signed on their behalf, regardless of age and physical abilities. Even those individuals that will not be playing (spectators) must sign a waiver (i.e., grandpas, grandmas, uncles, aunts, etc.). If an individual does not have a valid waiver on file, they will NOT be allowed to enter. NO EXCEPTIONS. Waivers are valid for one year.
