Stop in for a cup of coffee

I have to do a shotgun qualifier this week. Thursday I think. Gonna be brisk. It is 3F degrees here this morning. We shoot rain sleet or snow. Thinking about actually using my 12 instead of my twenty. A little guarantee against frozen clumsy fingers. That extra bit of shot and oomph can sure help. Might be the difference between making the cut or not? We sponsor a youth trap club. Sign up is tonight for the season. We anticipate aprox 110 to 130 youth signing up. God is Great Youth Trap Club out of Farmington/Prairie Grove Arkansas.
Lots of little shooters, sounds worthwhile. How long does the season go for?
