You really should already have some solid eye gear for the winter. Glare off snow and ice can be brutal. But we're changing the clocks, and considering the weather, it's about that time we see the transition. Heavy winds and pouring rain replace the snow and sleet, but the periods of sun are always perfect. Prepare yourself for those mini mid-day breaks for your brain. And even the pick up games after punching out.
Don't worry, those 20 degree temps will turn to 40s, and even better. It will be a miracle for your mental sanity and your fitness-game. Just be ready for when it comes.
