I believe St Francis of Assisi said, “it’s in giving that we receive.”
I think this is a win/win. You grow the fanbase, give some people a thrill, and pack the stadium…in the subject line header of the email, I’d say “we are looking for your help to shake down some thunder.”
In the movie It’s a wonderful life, it’s the genius of George Bailey that he thinks of the other person? And it comes back to him in spades… just some food for thought.
