What is the secret to finding backdrops for location work? Right now this is all a hobby for me and I've notice between this site and flickr/strobist that most of the location photographers seem to always have the right background and composition. I noticed some of those guys get right everytime. Do those guys just ride around searching for spots to do shoots? When they find the locations do most of them just shoot without a model first to get a feel for the location? Whats the secret? Fill me in!
