Rainbow in Back Yard

Late yesterday afternoon we had a rainbow in our back yard. This is a poor picture, but I hope you can make out the outline of it. It goes from the lowest leaves on the oak on the left, over the gazebo and seems to touch the oak in the foreground.
This is the second time I have seen a rainbow in the back yard. The other time it was brighter and in a slightly different place.
Amazing!A special gift, even as on the coast people are waiting for Hurricane Issac.
