Less dangerous than going into the ghetto at night for ANY reason.
...Better take a flashlight though.
Not very. The only real danger aside from getting lost is humans.
I don't know how dangerous for you, but for me, likely it's fine as long as you stay away from he areas inhabited by inebriates. Otherwise, you're not going to stumble into a moose as they stand out of the snow, and they'll be laying down anyway. In the summer it's all daylight so you're good as long as you make noise to keep away bears.
Extremely. However, if you have a reason it's safe as houses.
I don't know.....try it and let me know how things work out!
The teddy bears will get you and invite you to their picnic!
Take a compass and a knife and you should be okay
Not all forests are dangerous. Some come with well lit paths
