There's a shoot at Collin County Bowhunter's Association Sunday...I'm sure someone there can shoot with you and sign your card.

Call in advance and see if someone will be available or take Timm with you, with a little luck you can sign each other's card!
BTW, I might bring Jadyn & Liam up to the shoot too...would be good to see you guys so let me know if'n y'all decide to go.
