We took a trip at the end of last month to visit the annual Pumper & Cleaner Expo in Indianapolis, billed as the "world's largest annual show for environmental service professionals." The show is being renamed to WWETT, which stands for "Waste & Water Equipment Treatment & Transport." 

However the show's name is glamorized, no one will argue that this industry thrives on human waste and how we deal with it. You can imagine some of the other more humorous and earthy names for the show! 

No matter, something like 4000 businesses from all over come here to buy, sell and get educated about the latest equipment and treatments systems related to keeping sewers, drains and septic systems performing. Despite an outside temperature whose daily high was a single digit, the show was a great opportunity to listen, learn, and meet lots of nice, hard-working entrepreneur-type folks who enjoy making their living taking care of (ahem) "environmental services." Hey, it's recession proof!
