As we got closer we decided that it was a phenomenon due to the still weather; lack of wind allowed heated air from the refineries to travel straight up, like chmneys or tornado's tails. Interesting to watch, to the point that we had to turn off our book on CD - Malcom Gladwell's What the Dog Saw. And that book is hard to turn down.
WeFF is a feast for the eyes, a bonanza for the buyer, and our happiest day of the year. We earned more in one day (10 to 4) than we did in FIVE tortuous days (and one evening) at Convergence.
