I see no reason why someone could not change. One one category can be entered ata time. As long as it fits the criteria for classification switching should be okay. If you do please PM me. Also if you change in the next day or two I may not be able to do the changes in the forum as I am about to take off into the never-never land of lousy backcountry cell service.
We parked the trailer on the top of a canyon wall rather than down in the canyon. I am connected to a tower 30 miles away. Sort of. It is hovering around -112dBm, plus or minus 8 or 9.
