[Question] I can't find brown lentils anywhere! Does anyone know where to buy them?

I live in Los Angeles. I've been to a sprouts, Trader Joes, 2 Whole Foods, and a Vons/Safeway and I only see red lentils, green lentils, black lentils. In fact, Whole Foods has 365 brand versions of red and green lentils. Am I out of my mind or are brown lentils impossible to find!?
