To wave down a yellow cab can seem like an easy thing but sometimes they just down show up, and that´s usually when you really need them. Or, they´ll show up but with the out of service sign lit.. Waving down a yellow cab at wall street with a Fjällräven Kajka on your back is easy peace though! We tried to get some product shots of our backpacks and i think we stoped 20 cabs before we where done, haha! If you have a hard time getting a cab you should definitely consider getting this bag!
