I know it’s not winter, but I’m answering this.
1. Only be able to build a snowfort. Just building a snowman isn’t enough.
2. Montana! Even though it’s super cold (Read DukeSilver’s answer), I’d love to see snow (I have seen snow before, but I wanna see it for the rest of my life.)!
3. I’ve never tried both, but probably ski. I don’t know, though.
4. October. My birthday is in July, and I do NOT want Christmas near my birthday. And if Christmas in July happens to be on July 25, welp, game over for me. My birthday would be the next day, and my grandma’s birthday would be on that day!
5. A squirrel. You get to eat acorns! (I’m saying that only because I’ve heard about acorns being toxic to humans.)
6. Keep summer break!
