At the recently-ended "world youth day", Argentinian Auxiliary Bishop Oscar Minarro "celebrated" Mass on the beach. The venue was bad enough, but was probably the least of the problems with that Mass. The bishop was vested not as a bishop, but as a beach bum. That is, he wore shorts and tee-shirt. As he consecrated the Host, he remained seated in a beach chair. There was no table to serve as altar - no platform whatsoever. Instead, everything was on a beach towel right on the sand. To say sacrilege occurred would be quite the understatement. Certainly the young people in attendance were ill-served, as they witnessed a successor to the Apostles treat the Holy Sacrifice of the Mass in a flippant, jocular manner, devoid of reverence.
I would seriously caution all parents NOT to allow their children to attend these affairs.
