I,ve just completed a ten day walk from Applecross to Pitlochry
crosscountry with one food pickup. In that time I only saw two dead
deer,both through broken legs.I saw no evidence of dead frogs etc. through foul water.My travel tap filter was never used,so much for all the stories that appeared previously.In my opinion the Highland water was as good as ever so don,t be over concerned if you are going into the Highlands.
