We arrived about 12:30 PDT. Hot, very light breeze, and sunny. Lots of wasps buzzing around but I couldnâ€™t see any nests. The field is drained, but the surface still saturated. Rice seeding heavily. Sara did veg height while I attended to the tower. I installed some fake batteries that Joe made to feed line power to the camera. The camera and the autocam program started fine.
