Monday June 20 - Day 50: I spent the day purifying a batch of PA and cleaning all the beakers for storage. I went all over the property to ensure that it would be presentable for today's visit. There was a 37kg pile of aluminium powder on plastic sheet I was unable to move so I covered it up as best as I could. There was also a lot of stains on the work bench in the barn I was unable to do anything about. Then there was the 1,8 tons of ANFO bags and equipment stashed in the spider cave. I covered it up properly but she would easily notice the diesel smell from the bags and uncover it if she went in there... The fate of the whole operation relies on her not noticing. She came to the farm around 20.30. We talked for a while and she said she wanted to stay the night, sleeping in one of the outhouses. It was late in the evening so she wanted to spend the next day getting things from her storage room. I said it was fine and I fed her a story about me having to salvage much of the fertilizer for long term storage, seeing that I would not be able to sow the planned crop (sugar beets) due to too much rocks in the soil. I needed her to be prepared in case she went into the spider room. I just hope she would let me know if she got suspicious the next day so I could take necessary action...
