[Power Rangers] With an entire planet to conquer, why does Rita Repulsa always attack Angel Grove, California?

Because she knows the Power Rangers live there. Rita's plan is to destroy the Power Rangers because they are pretty much the only obstacle towards her conquering Earth.

And most of her attacks are psychological, meant to throw the Power Rangers off their game by messing with their personal lives. It's not necessarily the best or most effective tactic, but you try telling a millennia old witch that she's being impractical, and see what kind of response you get.
