I was a very very late Baby (Mom was 40), so a lot of the stuff your Grandparents are passing on I learned direct from Mom and Dad. Darn it, I miss them. They were the folks who got the "be prepared" mindset drilled into my brain.
That's me as well. Fortunately, we have a family reunion every year and I sit with my Aunts and Uncles and ask leading questions, and listen, listen, listen. I got to butcher the hog last year, and will get to do next years hog also. I'm fortunate to come from a large family, over 90 first cousins just on my Dad's side.
