Not to be a smart a$$ here, but, I don't understand canning.
While I've never sought out canning websites, I've seen a lot of posts over the years on different forums where people get all excited about canning or 'canning season'. If I had to guess, its probably in the 100's.
YET.....
I have not seen ONE post from someone all excited to open up and eat something they canned years earlier. NOT ONE.
Is canning much like sitting on a lake fishing? It's not the need but the moment?
What I have seen however are 'urban explorers' that explore long abandoned houses with canned goods still in the basement.
