Forget summer or spring, McKenzieâs favorite season of the year is probably Girl Scout Cookie Season. The 11-year-old is nearly finished decorating her cookie booth and is eager for the first day of cookie sales â Sunday, Jan. 31 â to arrive so she can start selling friends and strangers on the merits of Thin Mints or Lemon-Ups. She also has a message for her Girl Scout sisters who might feel daunted about selling cookies during a pandemic. âWe can do this, Girl Scouts! We have this Cookie Season!â McKenzie said enthusiastically. COVID-19 is here, but âwe can break through that barrier. We can do this!â
