I think the Lone Star Challenge is going to be the best match of the year. It's too late to sign up, but you could volunteer to RO and watch the festivities (i.e. me missing a lot of targets)
since it is a private range, volunteering to help run a match would prob go a long way towards getting invites to come shoot it. and they may let the ROs test fire the courses before the match, so you might get to shoot it for fun
here's an announcement for it, since they don't seem to have their website updated
