As you can see in my avatar I consider waxing and tuning an essential part of the winter experience. So much so, I start in Florida around September when it's 95 degrees out.
There is a degree of concentration, contemplation, physical hand skills and inebriation required to get good results. There is no better way to spend a few hours on a dark winter night. You will be at one with your skis, they will obey your every command the next morning. Your wife will appreciate her finely tuned and waxed skis to the point where she will bring a fresh beer out to the garage (or rented condo utility room in my case).
But don't track the wax into the living room or you lose the cleaning deposit.
