I thought this image of the date market was amazing. If you're a date fan, this is the place to be!
According to Wiki: "Buraydah (the capital of the province) is one of the biggest dates producers worldwide. Each year (in September), a big "dates season ceremony" is celebrated, at which a lot of people come from all over the GCC countries to buy their yearly requirement of dates. It also has the biggest camel market in the world.
"Unaizah (the second largest city) has created its own "dates season ceremony", called "Unaizah, the kingdom of dates", the municipality of the city has paired it with other festivals being held annually, to promote a good tourism reputation."
