For the PI crash, I need a unit to block traffic for me, two cars. Do I have a nori unit en route to this PI crash? 18-51 from Walnut South. Clear. I need somebody to block southbound at Brandon Court for now and someone to block northbound at Winslow. North 1797 and en route. I'll take Winslow. North 1768, Henderson and Miller, all block at Brandon Court.
