The best times to go for this cache is from 8am to 2pm or anythime after 3:30pm on weekdays. On weekends, anytime is fine exept at night since it is placed pretty close to some neighboring houses. This sidewalk is used by many students, including me, to travel to school and back so if you want to deal with lots of muggles, I recommend going at the times listed.
And yes, I made the title Halloween themed, but the cache isn't.
Dedicated to srmkona, my dad, and Halloween 2017!
