I have lots of experience in a wide variety of venues in three countries and many cities and towns. Colorado has such a wide variety of venues and many natural locations to choose from. If I haven't shot at your venue(s) before, chances are I have at somewhere similar before (including dark churches). To make sure there are no surprises and to scope out potential photo locations I always try to show up to a new venue early. I do not generally travel for rehearsals for this purpose though. Although it's reassuring to know a photographer has worked at your venue before, I can honestly say that some of my most creative work has happened when I see a place for the first time with a 'fresh' eye.
