Steve - Don't know where in Nv. you live or what you have heard but around the Reno area stores are and will stay open, drug stores will be open, gas stations will be open and people who work in essential jobs will still go to work, this includes truck drivers who delivery the food etc well still be working.
In Calif it was a post with a title like yours (on another message board) warning people to buy all the food etc. they could before they couldn't is what led to the panic buying and hoarding. I am sure like in Calif. and other locked down places food and other supply's will still be there after the panic buyers have enough or run out of space to store everything they don't need. People will even learn that other people will share. After every body stops the panic spreading there
are only 3 things certain about this virus, 1 - you might not get it and just be a bit inconvenienced like others, 2 - you might get it and recover and be inconvenienced and 3 - you will get it and die and then you won't care.
