Mobile health clinic, Remote Area Medical (RAM), plans on providing medical care for more than 2,500 people in the parking lot of the Wise County fairgrounds in Virginia over the weekend, free of charge. On Friday, the first day of the offer, around 1,500 people have already lined up to be treated by founder Stan Brock and RAM’s volunteers, ABC News reported.

“In this economy, work is real hard and money’s real tight,” thankful patient Paul Ramos told ABC. “Last three years, I have passed it up. I guess because I am prideful, but this year I was able to come.”

Unfortunately for people showing up to the fairgrounds late, RAM works on a “first-come, first-serve basis.” Patients receive a number and the lowest number is seen first while higher numbers could be waiting around for days.

RAM clinics offer dental work including cleaning, fillings, and extractions, vision care including eye exams, eyeglass prescriptions, and eyeglasses made on-site, general medical consults, and women’s health exams, according to WBIR 10.

The non-profit, airborne relief corps was founded in 1985 and consists of volunteer doctors, nurses, pilots, veterinarian, and support workers. “You’ve got 40 or 50 million people that are in this category that don’t have insurance and they can’t get the care that they need or they can’t afford it,” Brock explained to ABC.
