Cape Coral letter carriers, front, from left, Bruce Altman, Carolyn Wetzel and Michael Daniel proudly display their Million Mile award plaques. To earn a Million Mile award a letter carrier must have at least 30 years of accident free driving. A celebration of their accomplishment was held today at the Cape Coral Post Office. All three letter carriers attribute their accident-free success to defensive driving. Distracted drivers, seasonal visitors asking for directions and the location of mail receptacles on heavily traveled, major thoroughfares are challenges that 112 Cape Coral mail carriers face daily.
