Today I received a shipment which was left out in direct sunlight by the USPS delivery woman, immediately adjacent to the covered parcel locker I have provided for this purpose. She's asked me in the past if she should use the locker (which is clearly marked with USPS, UPS, and FedEx logos) and I told her yes. Of course, it may have been a substitute carrier today. Fortunately, I was home and even more fortunately, today's shipment is an audio component rather than some LP records. But now I'm wondering, as the heat index here was over 96 degrees today, what would happen to phonograph records left out in heat (and direct sun) like that? Any thoughts and/or suggestions?
