The current thread on 'horse winding' has strayed some way from the original subject. Could members bear that in mind when replying to messages - if you are picking up on a different, perhaps indirectly related, thread in a message, please change the subject heading. Otherwise, anyone checking the archives for material on 'horse winding' is going to end up with stacks of unrelated messages on bad air and radon - not what they expected.
