Still doing a little planning for my trip in June. My friend and I are traveling through Scotland from Edinburgh to Inverness and back again, going to Isle of Skye and Stirling on our travels. We will also be doing a Whale watching tour or the Three Island tour. I have read on several posts, blogs, sites, etc... to take along a weatherproof jacket. I wanted to ask if the coat needs to be a thick warm jacket or just a thin weatherproof jacket just to keep dry. Any suggestions?? I did buy my shoes - Merrell Moab 2. Great shoes!!
