Usually is, ground is frozen and you watch the balls bounce 20 yards in the air when you hit a fairway/green/cartpath/rock at that point its all the same lol
no body checks though which is a win
We play this course near RI/CT line that never closes, owner will even snowplow the fairways. But there's a par 3 where you have to bounce it off the frozen pond and then it has to bounce just short of the green to have any chance of staying on. Anything else it's a goner.
I usually play all winter if course is open, but below 20 is rough.
