Hey, check out this website, it has photo guides for a number of really great places. I've never read one, but they look like they would get you on the right track, maybe reduce some scouting time, and fuel costs, especially if it's youre first time to the location.

You will find a list of locations that have published guides on the left side of the page. Check it out.
