I arrived about 10:50 with Patty. It was a mild, sunny day with a cool breeze from the west. The fields have been planted but are still dry. I talked to Jim the other day on the phone and he said they have been having problems with geese eating the seed. I couldn’t clearly see any rice coming up yet. The soil near the berm has a lot of cattail debris mixed in. We thought about putting the tower back in the field, but decided to wait to see where the rice comes up.

The leading edges of the sensors were covered in dust.
