CEA Raleigh, Premier Clayton Shockers, Cheer Carolina, Elite Cheer and Dance, and Carolina Legacy are all within an hour of where I live.
I've been with most of them and can tell you that they all have their ups and downs, but where I am now is the best for my family :]
I'd say that some of the gyms like to think that they're rivals of others, but honestly they can't keep up for the most part. My gym now doesn't really worry too much about "rivals" or the other competition really, we just strive to do our best and hopefully come out on top. [:
If I am willing to drive 1-3 hours, you can add CEA Sanford, CEA K-ville, CEA Greenville, EC Cats, Aviators, Infinity Cheer Empire, Cheer Infinity, Cheer Mania, Victory!, Charlotte, Charlotte Extreme, etc. I'm sure there are more.
NC is packed with gyms....
