Welcome to another Skywatch Friday. Yesterday, Kew Gardens was celebrating its 250th year with free entry for all. So, having heard the announcement on the radio and at a loose end I headed down there and joined the queue of cars for parking. I've never seen the place so full of people out for a New Year's Day walk; lots of families out making the most of the freebie. I was pleased to see the new treetop walk, but have to say it doesn't compare to a similar one I braved in Western Australia which swang from side to side!
