One group of these volunteers has been called into action by the city of Midland. They're members of Team Rubicon. They call themselves gray shirts and the people who wear them are always ready to lend a hand. "We respond to disasters and give medical assistance. Since the pandemic we've moved into feeding America and testing sites. Now that we're into the vaccinations we're putting everything into this effort to stop the pandemic and assisting where needed," Jarrett Brown, field leader said.
