Wow, that's too bad about the carport and your son's Camaro.  I know how he feels about his Camaro....I used
to have a silver Z-28 years ago.  Loved that thing.  Did the carport collapse under the weight of the rain or was
it wind, or did something else fall on the carport first?  (Just full of questions, I  know.) 

I hope the insurance covers it...you would think it should.
