I live where there is a lot of lightning (west central FL) so have had near misses where the flash and sound came at the same time but the incident I remember:
I worked at a payroll company. One of our new clients was a landscaping company and in the first week they had an employee hit by lightning, and that one incident was more expensive to the workers' comp plan than the rest of the year combined, all companies. Poor guy died and not fast, it was heartbreaking. I also learned in that job that seawall building and underwater welding were our most risky clients (highest workers' comp cost) followed closely by racecar drivers.
