Alien Space Visitation at GLSKS...
Nothing was heard during the night, although some locals reported that at about 2 am their pets acted in unusual ways. One business man, who lives near the beach, did call the police around that time to report a "intense, low-pitched humming sound." The following morning, the following structure was found on the beach.

As you all know, it is likely that our first intergalactic contact will come in a mathematical formal since math is a universal language. All of the above, along with the appearance of the symbol "Pi" makes it almost certain that aliens visited the Great Lakes Sea Kayak Symposium during the night. None remained for rolling lessons.
