I haven't thought about it yet because I'm not a fan of the cold and in NY, winters can get very cold.
However, at this point, I'm hoping I'll find the motivation to at least do some indoor mirror practice.
Since you said you struggled with your swing all day, I'm curious how that translate score-wise for you. The reason I ask is because at the outing I admired how fluid your swing looks and what a "bad day" with a swing like yours looks like.
I plan on doing a lot of work on mobility, flexibility, and strength. I believe we have a dome to hit in a couple of towns away so I hope to do that at least a couple of times monthly so I don't lose this swing that finally seems to be working.My shot dispersion, yardage gaps, and short game have all been getting much better so I hope to continue that trend.
