In a continuing tradition of "Guiders on trails" here's another one! http://www.cancerresearchuk.org/support-us/donate/francis-crick-institute/DNA-trail I've just realized this is on and it closes on the 6th, so it would be next Saturday (29th Aug) if anyone is interested. Usual plan is meet at HQ around 10am, wander round trail, and disappear when you've had enough. This could be lunch time, tea time or even later if you like! We're a friendly bunch, so please don't be nervous if you've not met us before. The more the merrier! No cost, apart from train tickets and food/drink if you want it. Over 18's only.
