Hello!
Vernon Paul Adams, the man who created this font (and many other free fonts), passed away August 24th, 2016. You can read some thoughts from his wife, Allison, at SansOxygen.com.
Also, if you wish, you can donate whatever you like at SansOxygen.com/donate/ or
www.youcaring.com/vernon-adams-642574, in respect of his work and family, or as a "Thank you!" for using his work in your design.
As a side note, I am not in any way affiliated or related to Vernon, his family or friends. I just stumbled upon this as I was doing research for a project based on the Pacifico font.
Thank you and rest in peace, Vernon.
