Last summer (2001), some of us AGDs were "tossing around the idea" (pun intended, I think, lol) of making the acorn as our symbol. The pearl is our jewel and the squirrel is our mascot..so..we in the new "GC" chapter thought about having the acorn as our symbol.
I am not familiar with AX0 so I wouldn't know what to suggest, but, hey, perhaps y'all could come up with an 'extra symbol".
BTW, I found out at our Christmas party with my hubby's office that a co-worker's wife is an AX0! I think she went to school in/around Lynchburg.
Good luck!
