Recently, authorities in several jurisdictions extended the stay-at-home orders implemented to control the coronavirus pandemic. New Jersey and Pennsylvania extended to May 7 and 8, respectively, New York State to May 15, and Wisconsin to May 26. New York Mayor Bill de Blasio stated that his city wouldn’t open until July at the earliest. Leaders in Los Angeles, Philadelphia, and the state of Washington have also indicated that the lockdown could continue into summer.

It will be hard enough to convince people to adhere to these policies for weeks or even months longer than they initially expected. It will be even harder to make them do so amid summer weather.
