Selling or buying a bike locally is safer than going to the grocery store.
At the store.....you cannot control the crowds
Meeting at an empty parking lot, and being smart, like others above have indicated is WAY more safer.
Plus you are outside.
I am not making " light" of this virus. I am as cautious/nervous as anyone. The Grocery store is the place where I have the most concern.....
Most people are smart. They keep their distance and wear a mask.
But not ALL do.
Be/stay safe my friends.......
