I have a brother in Dallas and he doesn't take this very seriously even though he is 50. Why? Because his wife tested postitive for the antibodies (she was very sick in March) and he tested neg. was never sick like her and says he has "superior genes" sigh.
Anyways...I think if you do not have a deep freezer- even if you get just a small apartment size one...you are being smart. I do know they are very hard to come by....and on backorder. I realized in the middle of lockdown how much I needed that extra freezer space and was lucky to get a small one off Amazon...but I had to check every day and my first order was cancelled.
I also think that when you go to the stores now, even if you have what you think is enough at home, pick up an extra pkg of tp and paper towels, yeast, disinfectant (so hard to find even now- supplies will be back up I heard in July). One thing I found was I enjoyed doing puzzles. But I only had one and when I finished it, everywhere online was sold out. I finally got one in town, called the place and they did a curbside delivery for me.
But this time I am stocking up on those!
I am still adding to my preps and also dropping off items for my son and dil - they work all week and do not have the time to find all the things.
Oh, I also bought a Brita pitcher (not that brand but a nicer one) so I don't have to worry about stocking bottled water. I still keep it on hand, but that also means less trips to the store.
Gather everything you can think of in the time we have for home projects, hobbies, comfort and to save trips to the outside world when/if this hits.
