I've recently traveled to several locations that all outdoor photographers have on their "gotta have" list and what struck me is that the most important thing in your camera bag may be an extra amount of patience.
As the world becomes more and more connected, don't think you are the only photographer out there who knows where the great iconic photo spot is and what time is best to shoot it.
I try to do my best to be courteous in these kinds of situations, work with and around my fellow photographers, and give up my tripod spot after I am confident I have the shot I came to get. I hope everyone else does the same.
I am also kind of kicking myself for not taking a photo like this at sunrise in Monument Valley, Arizona where I was literally in a line of about 100 tripods. I wandered off and found a much better location to shoot from where I was the only one for 100 yards around.
