Are you positive that Fisher was a member of the GPYC and NOT the DYC? If so, I will change the burgee shown on my page to show a pic of the GPYC burgee.

Besides the letters GPYC the burgess of the NYYC and GPYC are similar: both are blue with red crossing red stripes with a white cross in the center, (The NYYC stripes run north-south and east west, the GPYC stripes rune nw-SE and SW-NE)
