So I’m ok to go to Walmart with the unwashed masses but taking a walk around the block is a no-go?
yes.
you will be able to walk around the block, just keep moving
Just the opposite, walking outside for exercise is OK, buy stay 6 feet away from others.
Visit stores only for critical necessities such as food or medicine.
Walking, biking, hiking, fishing, hunting, running, and swimming are all specifically enumerated in the executive order as being allowed, as long as you are social distancing.
