I have a pear tree in my front yard. I know it is a pear tree because it produces pears. This month it is in full bloom. I have another tree in my back yard that is also in full bloom (left).

Not only do I not get any delicious fruit from this tree, but I also do not have any more clues to tell me what kind of tree it is.This video will show you how I found out what kind of tree this is by searching Google ... not by entering text, but by entering this image in the search box.
Now if Google could just tell me what kind of dog Sasso is ...
Google thinks Sasso looks like this guy:
I cannot disagree.
