#15 and #16 incorporate the history of our logo (Canadian Geese) and reflect our agricultural area. It is elegant but we are not sure we want to be locked into "the geese."
#14, 13 & 11 look too much like Bally's or a bank logo.
The reason I use Goose because the brand name it self: Yuba City. I did small research with YUBA City and found that goose is one unique identity for Yuba city. Also Goose is something interesting to explore as an elegant logo.
I try to stay away with explicit objects such as racquet or people in sport because they don't strong enough used as your identity.
