In a previous post on Storage Terminal Industry Trade Resources I provided a partial listing of useful resources. I ran across the Tank Storage RSS feed again the other day and it provides a good aggregation of goings-on in the industry and a very good events listing.
Another go-to resource is the Castagra blog authored by Tatsuya Nakagawa, VP Marketing & Strategy. Tats regularly posts to relevant industry groups on LinkedIn and other sources. He got quite the sense of humor for a guy in a tough business!
