Luis,
I recommend you go. I went last year and would go again this year, but I have conflict that weekend, otherwise I would be there. The promoter, Chris Hale, does a good job and has some cool awards lined up. Also, it's in conjunction with a 1:1 car show, so there is a lot to look at outside the model contest as well, along with food vendors, even a beer garden. It's a good time.
