Travel Challenge

Here's an invitation to set fellow bloggers a specific task to complete when away from their desktops on location.

To get the ball rolling:

Delhi - discover Sultana Raziya's tomb in Old Delhi

Damascus - where's the sign that reads 'severe your connection with the created and establish a connection with the Creator'?

Istanbul - find the obelisk in Sultan Ahmet

Andalusia- spot the 'baby chick tears' dining out in Granada

Keep those suggestions flowing.

I lost my heart in... South Africa - Rageh Omar

Isabel Choat interviews BBC journalist Rageh Omar in the Guardian's travel section.

Where do you want to go next: I am fascinated by Iran. I've worked close to the border but never actually been there and it's somewhere I'd like to get to know, especially Qom, where you find the main seminaries.
