Put away that charcoal. Here's a different kind of grille for your patio. My, how times have changed. Back when vinyl records were king and a 25-inch-diagonal TV screen was considered big, here's how you had a good time in the backyard: a keg of beer, burgers on a charcoal grill, and your roommate's big, ugly speakers (carted out from the living room) blasting Rush (Geddy Lee, et al) until the conservative neighbors call the cops. A decade or so goes by, and the fun gets more sophisticated: a cooler of imported beer (maybe a margarita machine), steaks on a gas grill, and a big, ugly boombox belting out Rush (Limbaugh) until the liberal neighbors call the cops. Today, it's likely to be takeout from a local BBQ joint, a mini-fridge full of hard lemonade, and steam from the hot tub mingling with big-band music from outdoor speakers hidden somewhere in the (twice-monthly manicured) foliage.
