Posted at 5:23 AM, Apr 29, 2021 and last updated 2021-04-29 08:47:41-04 (WXYZ) â Another prom season is here and the pandemic is still changing the milestone celebration for high school seniors. Schools are trying to navigate state COVID-19 restrictions while putting on an event that would traditionally have 400-500 guests. Currently, indoor non-residential gatherings are capped at 25 people in Michigan and outdoor non-residential gatherings are limited to 300 people. It's a difficult time, but schools and student leaders are charting a path forward while some parents are making their own plans to make sure students get their moment in the senior prom spotlight.
