I don't know what to say about my expedition yesterday with the British Lichen Society people - except I'm hooked! How I am ever going to manage to go a 'proper' walk now I don't know, and if I manage to get someone to go with me once, it's a sure thing they won't want to come with me again. It was bad enough when I was stopping to look at butterflies, beetles, botany and birds; now I'll be stopping every few yards to examine every fencepost, wall or stone that I pass. Worse still, not only will I have my binocs and camera hanging round my neck, but I'll now have a hand lens to join in the tangle of straps. I never travelled light before, but now I'll have even more stuff to jam in the rucsack - bottles of bleach and potasium hydroxide, massive lichen field guide and the compulsory hammer and chisel. Wow! I can't wait to get out again!
