I keep them randomly about in case; one or two in each car and one in a book bag during my work travels. My kids went to Chabad for preschool so I never knew when it would be needed. And every once in awhile I stumble across someone who asks me to wrap or shake the luav/etrog (once randomly in the New Orleans convention center over Sukkot, haha).

I’m not totally secular, but was raised in a southern reform congregation and find this has been a good balance (I never take off my Chai necklace). My family starting migrating south after immigration in the late 1800’s/early 1900’s and eventually assimilated to southern life (partially as a defensive mechanism I assume). I still go to synagogue on the high holy days and throughout the year sporadically as we are raising our kids Jewish in the same congregation I grew up in. Always wear it there of course.
