Canceled Flight to Tangier Island (TGI)

I was unable to go to Tangier Island (TGI) this past weekend. I was on standby and no aircraft was available. I am scheduled this weekend to fly the Skylane for an hour as a refresher because there is only a hour and a half window available. There is also a possibilty for thunderstorm. The weekend of the 26th of August I will not be available to fly because I will be attending a wedding in Pennsylvania. Sorry I will not fly there. You asking why, well I will be with a family of 8 and all the aircraft I fly are 4 seaters.
