Ok, I talked to my father again today and he said that upon further inspection it appears that portions of the crop have miraculously survived. He did lose crops on certain varieties, but it seems that other varieties only suffered 50% losses, which really is amazing. During bloom, 24 Fahrenheit is typically an 80-90% loss and he had a night of 24 degrees followed by a night of 20 degrees. So right now it looks like he will have a season. Certainly not a great one, but he will have a season. Thank you for the prayers.
