I guess Matt Day has had some sudden serious health issues. A GoFundMe has been set up to help defray the healthcare cost for his family.
He always came across to me in his videos as a very genuine, down to earth guy that really enjoyed sharing his love of photography with people through his videos.
I gave a small amount of money, and saw that there was no mention of it on RFF so far, so I figured I would try and help by getting the word out on here. (I am not affiliated with this GoFundMe campaign)
