From the flyer:

"Friday, April 2
Copper Coaches Clinic #1 - 12:30 pm to 3:30 pm
Copper Coaches Clinic #2 - 5:30 pm to 8:00 pm

Coaches' cards will be available for purchase only at the Copper Coaches Clinic for $30.00 during registration."

Mike Juby can probably tell you if you can still get one from USAWKS.
