Up until approximately my 75th birthday, I always looked forward to the winter months because of the snow activities it provided. Sometime after 75, I became a "Sunflower" and starting following the sun-----BUT-----that also opened new doors, and allowed me to enjoy new places, people and activities during the winter months
The things I always enjoyed in the winter were Ice Skating, Skiing, Ice Fishing, Sledding ( downhill and behind a truck ), snowmobiling, dog sledding ( I have been trying to get Ken to take his lovely bride up to Jackson Hole as they have some great dog sled rides that include a dip in a outdoor hot springs at the turn around point)
Panda Bear runs a trap line in Canada during the winter months, which she enjoys and it provides a bit of income. This may have changed but check the Labrador and Manitoba regulations, as they use to have winter caribou hunts. Nunavut for Muskoxen. You should still be able to hunt Snow Geese, as well as cougar, fox, lynx, rabbit ---
These are all outdoors activities but obviously there are a host of things one can do indoors depending on what your interested in---but in line with the H/T forum, reloading, gun refurbishment, --
BUT--dont discount, following the sun during the winter months It can be a lot of fun sailing to and exploring each island in the Caribbean. You will run out of winter months before you run out of islands.
