This weekend a friend and I wandered down the block where a church festival was going on with food and music and a growing crowd of smiling people. The air was filled with gorgeous aromatic smoke pumping out of two hard-working barbecue pits. We got ourselves a couple of elotes (roasted cob corn slathered in mayonnaise, grated cheese and chili powder), washed them down with watery, tasteless beer (Michelob Ultra, to be precise), and hung out to watch enthusiastic musicians bust out some fine Tejano two-step stuff in sweat-saturated matching pink shirts.
