The Head Cretaceous Creature says we’ve never had to cancel an event because of the weather. Rain or shine, we will be there! There will be delays if there is thunder & lightning, but we’ll start eventually…bring a headlamp! As the USAT recommends, if there is lightning within 6 miles of the event, we will postpone the event until we are clear of thunder for at least 30 minutes.
