Name That Tree!

I took this picture earlier this evening..

This tree is one of the weirdest trees I've ever seen.

Someone told me it's a Bur Oak and that's why it has that solid

growth - and that thing growing out it's side it HUGE!!

Now I am obsessed with this damn tree!

To no avail I tried finding other trees like it on the net -

Can anyone tell me about this tree or trees like it?

This one is located in Elroy, WI.
