Unfortunately I dont think I will be attending this DO
I spent about 1hr shooting in the snow in LI on Thur night during the storm and it was tough. I was all dressed warm but my hands were close to numb after constantly removing my gloves to chage settings.
Also be careful with your equipment. I used a "cheap" prime lens and my D300s has weatherproof seals, kept the lens cap on when not shooting and pointed away from the wind.
At one point I tried to pop up my flash, but the snow had it stuck in place.
