You must pay first, otherwise you can't walk through the house, regardless if you want the tour or not. Mary Lou Gulley's house is large and eclectic with random objects being used in the architecture; anywhere from recycled bottles, car parts to real petroglyphs. It is definitely something to see in Phoenix cause it is such a unique home. Note of caution: there a very bumpy rock path to get to the house. Yet, my lil car was able to make it fine, by driving at a snails pace.
Overall it was a cool home to see, but not amazing.
