It's not often that indulging your nerdy side leads to you actually leaving the house, that is unless you're so enraged with your Kinect game that you throw the controller out the window. Aiming to give you a more amiable stretch of the legs: Nerdy Day Trips.
From pseudo-science arch-nemesis Ben Goldacre, this site pulls in crowd-sourced day-trip destos encompassing dorky fun from "the water-slide park" to "dead Victorian racecourses" ("And in the right lane Isimbard Kingdom Brunel is decomposing at a thrillingly rapid pace..."). Just click the various pins dropped near your 'hood to reveal pics, website, and descriptions, or add your own action by creating an account (in like, ten seconds) or using your Twitter handle -- if you don't have one of those, you're too cool for this site anyway. Spots in and around our cherished capital so far include a video game museum, a (formerly) secret nuclear bunker w/ a 30-ton blast door, London's first-ever red telephone box, the whole village of Imber (completely "stolen" by the MoD for use in war games), and an abandoned motorway junction on the M1 described as eerily post-apocalyptic, making it different from the rest of the M1 only in that it is a junction.
The site-runners are also promising a mobile app, plus features handling places to stay near locations, route planning, and more nerdishly interesting spots in other countries, thereby Kinecting you to the whole world.
