A recent Zipcar survey found that nearly 40 percent of Americans nationwide say that the first day of spring is their moment in time to roll the car windows down and start to enjoy the season. So, to encourage people to embrace this change in weather and spirit, Zipcar declared the first day of spring, which this year fell on Monday, March 20, “Windows Down Day.” Celebrating Windows Down Day is simple: windows down, radio up. We’re encouraging everyone to get outside and gear up for warmer weather ahead, even if just from their car window, and share Windows Down Day with us on social media with the #WindowsDownDay.
