Utah LDS Sports website can be a huge help to you! They have rules for games, posters, information, and much more on how to successfully carry out an LDS sports program in your area. Sports, if executed correctly, can be a very strong tool in your area. Especially with the YW. I have personally seen more inactive, or non-members come to sporting events than anything else in the church (well, maybe not more than girls camp). You may want to think about starting up sports if you think it is for you and the members around you.
