My wife shoots in our Tuesday Trad league every week. We have several women shooters and its not really competitive just a lot of fun. Thats really what its all about! My wife outshoots many of the men in the league but its the idea of making it fun. We change the distance and the difficulty of the shot (kneeling, sitting and turn around,) on every station. When we first started the league the women shooters numbered two. Now we have five shooters. Try not to make it very competitive. Try to attend some of the larger rendezvous and she will meet other women shooters. I started by introducing my wife to traditional archery 10 years ago at the Whittingham shoot in New Jersey and then later that year at the ETAR (Eastern Traditional Archery Rendezvous.
Best of luck to you both!
