I haven't been to World of Concrete, but will be going in the future.
My boss has decided that I am going to co-pilot our booth at World of Concrete and ConAgg (Orlando, FL).
I've heard all the stories though.
The thing to remember is for a lot of those folks, this is their own vacation. Most concrete plants are mom and pop operations. Dad dispatches, Junior is a driver and Mom handles the bookkeeping. In fact, one of our brouchures is called "Computer Systems Saves Marriage", based on a true story from one of our customers who saw their business expand so quickly that dad worked 5AM-6PM dispatching while mom worked 7PM-2AM doing the books (they had a young child at the time and couldn't both go to work).
While it is hard to replace someone, it is easier during the slow season (Jan/Feb).
I must say that these are among the nicest people I have met. Most took over the business from their parents. Some are 3 and even 4 generations old. Most of them started shortly after WWII, when the building boom started.
