This was probably taken 5-10 seconds before it hit and it took another 10 - 15 seconds for it to pass through.  Hard to tell how long it really lasted while you are living it.  I remember Rich telling me as I took this picture that we had to run to the basement NOW and then he looked back one last time and saw the tornado hit the pond and raise the water about 7 feet in the air.

How many minutes would you say this was taken before it hit?  How long did it take to pass through?  It's hard to tell distance, but this looks like its probably only 500 yds away!

 Taken right before the tornado touched down in the pond in our back yard.
