Dumb questtion, but I would imagine its still in the husk? If so, out of the sun and can breathe, it should be fine. A misting or two of water will help. If you can't get in in the shade, definitely go the cooler route with the drain open. Ideally stick it in the fridge. 120 ears should stack nicely, if you have a shop/garage fridge. I have helped pull a many of truck loads right before dark and headed to the farmers market and trade days a few hours before daylight. I think that drive before daylight gave it the airflow it needed. Repeat customers was proof that it was fine. I think getting it from field temp to room temp in a 24 hr period is sufficient but just an opinion. Keeping it from going through the initial heat process is key. It loses sweetness with moisture loss.
