Using a snowblower to get a good runway works well. Make sure that you layer your clothing and have plenty of hot liguids to drink. You'll find that your airplane will be a lot easier to spot on the ground if you have an engine failure although walking to it can be a bit of a chore if the snow is above thigh depth. A ski-doo (snow mobile) on standby can greatly simplify retrieval BUT, get a good grip on the plane if you're the passenger! With respect to airplane retrieval - be extremely careful of frozen (supposedly) streams and especially rivers. Winter flying can be a lot of fun - especially in the very early mornings; the sun stays low on the horizon and the winds are light. Our club has a guy that comes down from the high arctic in the summer to fly - you wouldn't believe the stories he has of winter flying!
