Dallas County Fire Dept put those red rings on the windows decades earlier
See if you can figure out why
Many City fire departments requested that the building manager place A SINGLE RED RING in a window of a building that did not have fire escapes, so the firemen would know where to place ladders to allow occupants to escape in the event of a fire.
More than a single red ring would have caused confusion for the firemen.....And perhaps your cranial rectalitus has prevented you from seeing the fire escape on the east side of the TSBD that goes clear to the roof....
