It is Springtime where I live. I know this because of the critters. They are on the move! One of them just looked at me the other day as if to say, "Uh huh. Silly human. I instinctively know when to go where. You need a calendar, and you marvel at me. Bwahaha!"
As for winter and the jobs, weather has impacted the early job a few times. I do few shops, so my ms-ins was only affected once. I re-scheduled a distant shop and lost all efficiency. Oh, well. More important was finding out just how understanding the scheduler was regarding the weather and timing and my little part of the world. Thank you, scheduler!
