I have a slightly odd but pressing question about grilling etiquette. My wife and I just moved here from Manhattan, where you don't need to worry about such things unless you're rich enough to have a patio or a yard. We weren't. But now that we live in the slightly more civilized milieu of Palms, we can afford a parking space-sized cement enclosure out back. You all know the arrangement: duplex apartments packed together like sardines, neck-high fences and zero privacy. We have done our best to nurture a vegetable garden on our plot, but we want more--we want to grill. The question is, are we going to alienate ourselves from our neighbors by filling the air with charcoal smoke and the scent of Vietnamese pork chops? How do Angelenos navigate this ethical maze? Or should I just relax and grill to my heart's content?
