We received a Mazo Beach invitation

We received a very nice invitation a couple hours ago to Mazo Beach. When I went back now to check on it and respond, it seemed it had vanished into thin air. I just wanted to let the person who was kind enough to invite us know that we're spending the weekend with my parents up in the Hurley/Ironwood area, so we won't be able to join him/them this time. Thanks for thinking of us!
