Ok, it is not all that spectacular since I am selling my truck to my mother but...
I told her that if she is going to buy it she has to pay me in bitcoins.
This is mainly to help her learn how to convert her dollars to bitcoins to help her get her feet wet.
Plus the usefulness of Bitcoin comes into play here. I will be out of the country with no access to a bank. She cannot send me a check. She would have to either go to my bank and deposit into my account or attempt some sort of wire transfer or come up with some other difficult way to pay me (or expensive using PayPal).
