It is a good source, but sometimes the site will look a little different when you get there. Some of the photos maybe older and vegetation might look different. We used it several years ago for a spot at Topsail Hill. Their picture showed lots of grass. When we got there, there was hardly any in that site. I've also heard of others mentioned about vegatation, such as bushes beign bigger when they get to a site. The view they thought they had, was different. But all in all, it's nice to get a somewhat idea.
