Random London Fact of the Day
The River Walbrook was the first of London’s ancient rivers to be buried beneath the city. It runs from Shoreditch down to the Thames, carving the valley between Ludgate Hill (St Paul’s) and Cornhill (Leadenhall). Today, it’s part of the sewer system, but you can still see where it (should) meet the Thames during storm conditions. At low tide, go down the steps next to Cannon Street Station and head west past the moored, rusting hulks on the foreshore. Voila, this blocked-up portal. Poet Tom Chivers is currently leading ‘pilgrimages’ along the Walbrook valley. They’re all booked up, but you can find out more here.
Good Cause of the Day
What’s more thrilling than shooting the rapids? Shooting the rapids in the dark. CLIC Sargent, a charity supporting children with cancer, is organising an evening of fun and splash at the Lea Valley White Water Centre this autumn. Participants get to complete the Olympic course four to six times between 8pm and midnight on 6 September 2013. It’s a team event, with nine people per raft, so get mithering your work mates now. To enter, you’ll need to pay a £20 entry fee and raise a minimum of £150 for CLIC Sargent. All equipment will be provided for you, and absolutely no experience is necessary. Sign up here.
For the sake of novelty, we were toying with writing today’s weather in verse form. Trouble is, there’s not much that rhymes with “early fog, clearing later to reveal blue skies that will remain all afternoon”. We tried “Burly frog, swearing gator to conceal two pies that will detain your baboon”, but that’s not the kind of scenario that our core audience would identify with. So, we’ll stick to writing in prose.
Early fog, clearing later to reveal blue skies that will remain all afternoon.
BBC Weather, is just way better at this forecasting lark.
