I totally agree. If you "feel" the atmosphere, chances are that you will be able to evoke it really well in your story. When I was writing my historical fiction that takes place in 1862 Vancouver Island, alot of it in the woods, I took my laptop up into my kids long-abandoned tree fort. I set up a chair and a little table, and went to the second "story", where I was completely surrounded by firs, cedars, bluejays and the smells were wonderfully intoxicating. I wrote the "lost in the woods" part up there. (Added bonus: nobody knew where I was!!) When I wrote the scenes that took place in the Salish native village, I had Salish ceremonial music playing in the background. THAT really helped me when it came time to write about a particular ceremony/gathering. It was way too much fun!!
