This is a freshly pulled lateral line. It will look like this for a few days and then just become a line. We will add sand and seed to the bad ones when it gets a little warmer at night.
You can see them moving plywood in this picture. They are done around the green and no longer need it. You can also see the machine pulling the lateral in.
They put the sprinklers in around they chipping green while they finished hole 9. They had to use plywood around 9 green and the chipping green because they were very close to the greens while pulling the laterals in. I have added some pictures with descriptions.
