I never did much outdoors in the winter when living in northern climes. Never was a skier, just a sitter-in-the-ski-lodge while paying through the nose for my kids' lessons and rental equipment. Until my daughter almost died in the sport. Never a fisherman or hunter, winter or otherwise.
In some of my adult life I was fortunate to live in warm, habitable climates: Malibu, California; San Jose, California; Austin, Texas; Tallahassee, Florida (twice); Jacksonville Beach, Florida. So, the outdoor activities in these divine, non-Ice-Age places were about the same all year round.
When I lived in the north in New York and Connecticut I spent a lot of my free time, which wasn't much, at indoor gyms and running tracks in the winter. In some years when working or after early retirement, I would manage to get to the Carolinas, Georgia and especially Florida for a couple of weeks on my own to canoe, while living out of my Magic Bus full-size van.
To have glorious outdoor winter adventures of skiing and trekking and camping and dog sledding and snowmobiling presumes one has lots of uninhabited land or is near to it. That's not the case for folks who live in cities or suburbs. Most such folks just plow driveways, shovel sidewalks, and then drive around on densely-habited and dirty snow-plowed streets. No picturesque winter wonderlands.
In my 60's in the winter, I used to travel a lot around the NY, NJ and southern New England areas covering girl's/women's basketball games and player interviews from the high school level, to the NCAA tournament, to the U.S. Olympic team, and be paid as a writer, photographer and videographer by various internet publications devoted to women's basketball. My business was called Magic Bus Sports and
HERE is my now moribund MagicBusBasketball YouTube channel. That was the source of my magic bus avatar.
(There is also one video on my
MagicBusCanoeing YouTube channel. I have dozens of canoe trips from all over the East coast on video, taken from a video camera mounted on a tripod in front of me, that I've never edited or published onto the channel.)
The past few years, my only winter activity in old age on fixed income is to stay bundled up in a partially heated house, which is now too expensive to oil heat, and to spend most hours reading, writing or administrating things on the internet. I still watch and post about women's basketball, and the NCAA season has just started. However, that's all just computer stuff too.
