Lightening Strikes, what do you do?

[Gre144]

In Denver we get a lot of lightning in the afternoon. Often coaches and umpires that I have worked with do not want to delay a game even if the lightening is right over the field. I always feel pressured to continue playing no matter how close the lightning is.
1)I was just wondering how other umpires feel about this topic(to delay or not delay)?

2)I was also curious if anyone has ever officiated a game where lightning struck a player or umpire?

3)What are the statistics of getting hit by lightning on a baseball field?

4) How do you know if the lightning is close or not?

5))Do you ignore the lightning and continue playing or will you delay the game immediately?
