When do you do your modelling?

[Prairie Trains]

Once the ground is covered in snow until it warms up and dries up in the spring. I will spend up to four hours a day some days and as little as a few minutes on other days. Some times in the morning some times in the after noon or in the evenings, in other words when ever I feel like doing some thing. In the summer I am to busy to even look at the layout.
