What you got in the mail is the "judging program", it is usually available online before you get it in the mail, and even earlier (a few days after closing) you can usually get the breed counts. I thought maybe the Indian Nations Specialty coming up would be close to you, but it looks like it's quite a drive since it's in Tulsa…and it's on a Friday...and the day before Halloween.
Once you find out who some of the people showing in the area are, it's likely that they may coordinate which shows they go to. If you can get on an email list, it will make it much more simple to figure out which shows to go to.
