Regarding rain, I remember building a food processing plant in Atlanta and was setting up a big concrete pour (50+ trucks). Sun was shining and all was good.
I was on the phone with my boss when first trucks started showing up telling him all was good. In a matter of probably 2 minutes a thunder storm rolled in out of nowhere, raining buckets. I was still on the phone and just said "SH#T! IT's Raining!". He was in CA and didn't believe me!
Trucks just started backing up and getting stuck in that good old Georgia clay one after another and started dumping their loads on the side of the dirt road.
One of my more terrible days and why I live in CA where the weather is more predictable!
Glad I didn't have the Cobra down there back then!
