In celebration of its 20th anniversary, the Green World Foundation invites you to leave your car at home, get on your bike and join a car-free day. The Cycle-lizing Bangkok Fest takes place on Feb 25, 3-8pm at Lumpini Park. There also will be information booths organized by the foundation on green living throughout the park, a short film about cycling and a live concert from Sqweez Animal, T-Bone, Kor Natthaphon, Apartmentkhunpa and Hugo before the program ends with a bike rally from Lumpini Park to Yaowarat Road, which will start at 8:30pm.
