I am contemplating a visit to Monument Valley in June and would like to get some information about shooting there. I guess the biggest question is at what point does it become desirable/necessary to go to the expense of hiring a guide? What are the options without a guide (places, times you can be there ect). And if a guide is hired, what should one expect to pay? Finally, I will be traveling with a camper so any insight into local camping conditions would be appreciated. Thanks!
