Keep Ringin' That Bell

A Salvation Army in Lafayette, Indiana discovered a nice gift in their donation kettle this year. A check for $11,000. But this isn't the first time, last year they received the same generous donation. How long will this go on? Who is this kind-hearted enigma? They wish for their identity to remain out of the public spectrum. I can say they've helped at least a few people live easier lives, and inspired many others.
