That wheel chair shot is in the basement of an abandoned building in Houston. It has been abandoned for a good 20 years. There is also a bank vault down there. I probably took a couple of years off my life being down there without a mask. There was also a radio station on one of the floors which people (including the employees when it was still operating). I obviously never saw anything there. One trip I went by myself...only ran into bums. I am always looking for new locations. I have been inside a couple of breweries, power plants, a paper mill, a skyscraper just to name a few.
I think the hottest spot in Texas is the Baker Hotel in Mineral Wells. I hear its hard to get into though.
