This is the site for the non-profit The Arts Alliance Center of Clear Lake (near Houston). They support local arts such as the local ballet, symphony, drama; and host art exhibits. They offer many art and music classes (watercolor, sculpture, making jewelry, guitar, etc.) for different age groups, from young children through adults. Their children's Summer Art Camps are very popular. (In fact, the summer youth classes are the reason I was accessing the site and saw the bad rating.) I don't understand the suspicion of the web domain since I know they've had it for at least a decade, and the organization and the site are squeaky clean.
