Free Frostys for a Year

I understand that if you go to your local Wendy's and donate $1 to the Dave Thomas Foundation you will receive a key-tag that is good for free frostys for the rest of the year.  (I am not familiar with the Dave Thomas Foundation if you have any input about them I would appreciate a comment.  You can check out their mission and value statement here).
