6th April And so the encirclement of Luton is complete! As I type this it occurs to me, that sentence has probably never been used before. To be honest, I'd hoped that last week we'd achieved this but, as I examined our routes, it became clear there was a tiny section across the East Coast railway line that broke my chain of walks. So we're back to finish what we've started. I have planned a walk from Heartwood Forest. It's the start of the bluebell season...at least that's how I explain the walk to Sue.
