Red and white illuminated balloons will dot the streets of downtown D.C. this evening during D.C.’s Light The Night Walk to support The Leukemia & Lymphoma Society. The casual 2+ mile walk through downtown steps off from Freedom Plaza at 7:30 p.m. with onsite registration opening at 6 p.m at the Woodrow Wilson Plaza at the Ronald Reagan Building.

Walkers carry illuminated balloons to celebrate and commemorate lives touched by cancer. The D.C.-area events are reportedly some of the most well-attended in the country, so if you can’t sign-up to walk on your own, there are certainly walkers who would love a sponsor. Not only is the event a good cause, but DCist is assuming that it will be a beautiful visual as well.
