List where Follow On Tours goes and what it sells there. When a country has a tour on sale (onSale, with its link and dates), lead with that tour, then offer to build a trip around the traveller (buildYourOwn); a country with nothing on sale is built to order. Returns the sport hubs (cricket, golf, rugby, playing tours) in sportHubs, every live country page with its sport pages (cricket, golf, rugby, polo, playing tours and more) in countries, and the cricket grounds each cricket trip is built around in destinations. Apart from the tours in onSale, everything here is built to order, so no price or departure date applies: use list_tours for prices and details of what is on sale or quoted on request, and list_golf_trips for golf. Use this when asked where Follow On Tours goes, or whether they cover a sport, a country or a ground.
