We did, and it was pumping 64 degree coolness. But it was nearly 100 yesterday. With the humidity, it felt like 109 degrees. The thing was working its fan off, but kept it around 80-85 until we turned on the lights. Instantly it jumped 10 degrees. We finished filming after midnight, and by then it was mostly tolerable.
We're looking at scheduling our next shoot either in late September or October.
