I grew up barbecuing in a big Texas backyard, but I don't have the same luxury today. Now I live in the densely populated city of San Francisco, where it can be hard to find a place for a grill. I've even come across a number of San Francisco denizens cooking on the fire escape! My friend Conway — who doesn't have any outside space at all in his posh condo — even lent me his gas grill, since he has nowhere to put it. Where do you grill?
