Having just given someone a list of things to do in London for Geeks, I thought I'd ask for contributions to build bigger, better, geekwalks. This is not aimed at any specific kind of geek but just covers lots of interesting things. If you have a contribution to make, give it a number between two of mine and I'll add it to the list. You can post the obvious if you like but it would be more interesting to have the less obvious
