Seven-year-old Robin Ratchford was fascinated by a postage stamp from Yemen, in the heart of Arabia. Thirty years later he finally gets to visit Sana'a, the capital, but finds the country's newest stamps hardly live up to the original.
It's famously easy to get disoriented in the narrow alleys of Yemen's ancient capital, but Robin Ratchford has two maps and counts every step. It makes his walking tour feel rather like a treasure hunt - but doesn't stop him getting lost.
Afghanistan is now far from any sort of tourist destination. But it was once a key stage on the 1970's 'Hippy Trail'. Robin Ratchford flies in to the capital finds that - on Chicken Street - all the same handicrafts are still on sale.
