DAVID HARDEN/Arizona Daily Wildcat Stars Rebecca Creskoff, Aimee Garcia and Bobby Chavez visit Sabino High School on Friday to meet the people they play on TV.

Niches. Everyone has to find his or her own. In the network wars ten years ago, Fox targeted the urban market with shows like "In Living Color," "Living Single" and "Martin."

Now, the WB is carving out a name for itself with its ethnically diverse programming schedule. The problem with this pseudo-network is most of its shows end up being below par of the USA Network's original programming.

Yes, that is a bad thing.

However, people must be watching the WB because that darned top-hatted singing frog and his endless supply of multicultural comedies have survived the winter ÷ "multicultural" meaning "not-entirely-white friends living in white apartments in a white neighborhood with whitewalls for tires." "Greetings From Tucson" walks a line, though. It jumbles up the white and the Mexican races and tosses them into one household, a surefire recipe for fully-diversified fun, no?

The sitcom centers around 15-year-old David (Pablo Santos) and his interaction with his Mexican father (Oscar Mechoso), his Irish-American mother (Rebecca Creskoff), his older sister (Aimee Garcia) and his uncle (Jacob Vargas). It's sort of a Mexican "Boy Meets World" type of deal.

So David is the product of a multiethnic family. The comedy doesn't avoid this fact, either. There are a few cheap-but-necessary race jokes so as not to ignore the technicolor situation. When David's little cousin gasps in awe that David's icebox makes ice on its own, the little cousin replies, "It must be nice being half-white." A step farther out and we see David courting the girl next door, a white girl whose mother mistakes David's father as part of a landscaping crew when he is just doing some gardening work in the backyard. Controversial? Not these days, because the typical conflict/resolution/canned laughter soothes any aching burns.

The outdoor scenery of Tucson looks like cheesy computer wallpaper downloaded at Roy'sComputerSkins.com, with sometimes-out-of-focus shots showing only stills of the Foothills Mall, adobe houses and the soaring Tucson city skyline. The show has borderline smart jokes in some places, but far too many of the typical WB half-laughs. Overall though, it's nice to see a show addressing race issues and having some fun with them instead of ignoring them as if they didn't exist. Hopefully, we get to see David press forward and we see this show progress as well as this pilot promises.
