A FEED to look out for on Twitter is @CityCorpHeath, the guardians of Hampstead Heath who post some great photos through this week. They get the award for Tweet of the Week with this… it’s a picture of that pesky blanket weed being cleared from Whitestone Pond. But what’s going on to the left? A sickly ambulance looks like it is being rushed to ambulance hospital.
