Maybe that is where people can go to ask Bitcoin a question?

Refreshing - some non bitcoin posts!  I can go for that.  Where is this?

Yikes!  Looks like snow mold.

"there are no fungicide treatments that work on snow mold in the spring when the snow melts"

so to treat it: "in early spring, the first thing you’ll need to do is gently rake the affected areas to loosen any matted grass. This will help the lawn dry and give unaffected grass room to grow."
