No luck finding the septic tank

Well Blaine and I went back to the cabin on Sat. We tried using a metal detector to find the septic tank but never could find it? We did however get the hot tub and old couch bed (that we couldn't fit last trip) loaded in the trailer, so no more junk pile outside the cabin. Now just to haul off all the junk under the cabin, one trip at a time. It's nice to have a trailer now. I did get to vacuum the cabin put more poison out and make all the beds. It was only 36 degrees and very foggy up there. I want to get the toilet fixed, it's no fun having to go behind a bush. We do have running water and hot water so that is good. We'll try again to find the septic tank. It's so quiet and peaceful up in the mountains and the air is so fresh. If anyone knows a plumber?
