Random London Fact of the Day
There are some 110 places in the UK known as Little London. Approximately none of them have a tube station. We rounded up some of the more buzzing Little Londons in a recent article.
Shameless Londonist Plug of the Day
Regular readers will have twigged by now that Londonist is the official media partner for Museum of London Docklands' 10th anniversary exhibition Estuary. We're really chuffed to be involved with such a promising exhibition — if you get a chance to go along (and it's free), let 'em know that Londonist sent you. It opens on Friday.
Good Cause of the Day
Founded in 2011, Artbox London runs free weekly studio sessions providing a hub and materials for artists with learning disabilities to create art work. The studio is led by volunteers who support artists to develop their own unique art practice and empower them to sell their work through Artbox London exhibitions. Tonight, Artbox London artists will exhibit and sell their work at Nati Gallery on Warren Street. Get to know the artists and possibly buy some of their work — they receive 60% of the money from sales with 40% going back into the organisation. Free, just turn up, 5-9pm
Single-figure temperatures in mid-May? To awkwardly mal-Frenchify a Star Wars quote, "These are not the froids you're looking for". To further quote the sage Mr Kenobi, in a scene inexplicably cut from the original films: "It'll piss down like billy-o come home time. And, Luke, watch out for that moderate pollen count". Use the Force. Better yet, use a brolly.
