If you’ve not been to the Metro Central YMCA this weekend is a good time to see this city-in-one-building for yourself, and their great green roof, with perhaps the best running track in the city (because you get to run with the skyscrapers). On Saturday they’re having an all-day green festival with loads of activities and even rooftop films in the evening. I’ll be talking about the City around 2PM on the roof as well. Do drop in.
