Convention Committee

CoKoCon 2018

CoKoCon is a traditional science fiction convention in Phoenix, AZ.

We'll be hosting guests of honor, an art show, merchant room, gaming, filk, parties, you name it!

The name reflects that it's the CopperCon and ConKopelli Convention, sponsored by both CASFS and WesternSFA. Phoenix phandom came together to support Westercon 70 (which was sponsored by LepreCon, Inc. in Tempe in 2017); the core players behind that convention are building on it together to move phandom phorward in 2018.
