Here in southern NM, we shoot year round. January can be windy and cold, 40-50's......during the day. Below freezing in the morning. The wind is the big factor, 30-40 MPH blows and gusts even higher. I used to live in Iowa, chicago, and connecticut so i know about cold..
We have called off a few matches due to rain. not often, we shoot the 2nd and 4th sunday, i can think of 4 matches we cancelled last year.
The Lubbock match will be indoors at the Patriot Range.. Should be cool.
