Dear Sir or Ma'am,

I wish to convey my sincere wish that the SEC allow the aforementioned ETF's to be approved for public investment. This is an important moment in our country. We must not allow this opportunity to pass us by. This new asset class is new and untried, true, but it needs our support if it's ever to be given the chance to succeed. Please do what needs to be done to make this happen.

Sincerely,
Marc Henderson
