I was in the business up in Rochester New York for 6 years and the weather up there is always extreme, rain, snow and cold. I never concidered it an obsticle for doing my work. If I did, I would be out of business maybe 8 months out of the year.
Sure, there are some things you need to consider that folks in warmer southern states can't even comprehend, but if you are in cold weather, you already know what they are, and your daily life is geared around dealing with it.
So, No..it's never to cold..it's never raining to hard and the snow is never to deep. Not for a full time business anyway.
