Took the kids out to Singapore Changi Airport for some longboarding fun.
There's actually a portion of the carpark at Terminal 3 that has been sectioned off at Basement 2, mainly for security purposes (so that car bombs cannot get close to the mall area, I guess?) that is nice and smooth to skate on and still has plenty of space to zip around.
In addition, the air-conditioning from the mall entrance just spills out, making the space nice and cool for skating in the tropics.
