What everyone neglects to acknowledge is the fact that about 60% of that money will be stolen by the I.R.S. On that happy note, carry on.
I actually think that if you give it "all" to charity, it's non-taxable...
So on that note, purchase an animal shelter and donate all the money to yourself. Then not only are you spending less than the 60% to help animals, you'd still have a large sum amount.
