What kind of winter or snow equipment do you keep in the trunk? NYC/LI winters can be rough. I usually do Prestone de-icer washer fluid, spray bottle, and "pre" icer, plus a space blanket (some have gotten stuck under bridges for hours). Additionally, I have 3 peak mountain snowflake tires, and I was thinking about a collapsible or folding shovel. And the usual, gloves, traffic vest, electronic flares..
