I'm sure you are well aware of planning, etc, but remember to tell several people where you're going, when you expect to be back, make check in calls at certain times, always have an escape plan
.
Solo journeys can be dangerous at any time of the year, but winter is when most go wrong. Typically, mostly due to hypothermia, as us folk in this country don't feel it ever gets
that cold,
that quickly. Also, if you are driving to a location, pack plenty of spare food and clothes in the vehicle, just in case you find yourself snowed in, and have to haul up in the motor for a while. No gas stoves in the tent, no matter how cold or windy it is, carbon monoxide is a killer in confined spaces, especially around ground level (where you'll be sleeping).
Be safe buddy, and hope you have a great time.
