At approx 1900 hrs on Wednesday evening Prince Frederick Units and CALS were alerted for a MVC reported serious in front of the WalMart in PF. M102 was in the area and arrived first on scene and began to evaluate the patients. M101 arrived soon after and assisted M102 with patient assesments. All patients were very lucky and were found to be pri-3's, CALS assisted BLS units with packaging for transport to CMH.
