[Lack of HP]

I hope this is a good place to post this. Being new to this site and now a Montana owner I would like to attend a rally. Living in Missouri not sure which one to attend. I would prefer to go south or east if possible.
Can some of you help this newbie out with some advise on which would be a good start and how to sign up. Sounds like a good time with lots of good information to be found from a lot of vendors.
Thanks to all in advance. Joe&Buffy
