Last night I was also trying to figure out why my legs were do damned itchy. Then I remembered the huge bushes of of stinging nettles I gleefully charged through with the strimmer. What I didn't realise at the time was that the strimmer was not only slaying the nettles but also flinging the bits at high velocity at my bare legs!

I live, I learn, I itch, I love the bite clicker...
