Ice cream in the Winter is totally fine. My signifcant other and myself frequently will get ice cream in the Winter. We both love ice cream though, so we'll eat it no matter how bad the weather is. Which I assume isn't true for everyone. I can understand how someone wouldn't want to eat ice cream in the Winter. To each their own. I'm fine with it, but I understand where people are comming from when they claim to dislike ice cream in the Winter.
Ice cream is great I love getting some during the winter and sitting by the frozen lakes, watching people skate by. Its such a wonderful feeling!!
