A Bug's Life

I'm doing a sponsored walk - not an organised one, as the dodgy joints mean I'd bad at reliably turning up on a specific day to do something then queuing with a mass of people at the official start point, but an, um, disorganised one? An opportunistic one? 18-20 miles from Ely to Cambridge, but in November/December so it will be cold and dark and probably wet. I'm aiming for Nov 24 but if that doesn't work I'll try the next weekend, and the next, until it happens. And that is how a bugshaw breaks the barrier to doing a charity walk. Sponsor me here if you like - I'm raising funds for Shelter - thank you!
