Water Level

I marked the position of the path using a whole lot of blue pins. After that, using a hose and some water I was able to measure and mark same level points on the pins, in order to avoid a sloping orchard.

Each pin now has a black mark

I used strings between the pins before, but the day after a couple of them had been chewed off. Maybe some animal got caught in them and needed to escape. So I use black marks now instead. The path should be just above those marks.

I also noticed that there is maybe 20-30 cm height difference between Mr. K's land and Mr. O's land, so in order to make a level orchard, my path starts below Mr. K to the east, and ends above Mr. O to the west.
