Did you know… our waivers have a lifespan? We’ve been open long enough now that we’ve reached renewal time! Yay for us! But this does mean if you’ve been with us long enough, you’ll have to resign our waiver. You can do this online or on your next visit! Please keep in mind minor waivers must be signed by the minor’s parent or legal court-appointed guardian.
