As Jane indicated, Captain Mike is pretty busy. When any of the crew including the captain are actually on the boat and the boat is moving, connecting to the Internet is not always easy. If you notice, even people who use laptops on airplanes don't try to connect to the Internet in flight.
There are various ghost stories associated with the boats. But the overwhelming response is that IF there are spirits present, they are watching over the boat, her passengers, and crew. They are like guardian angels. Personally, I consider ghosts in the same category as UFOs---I would never say they don't exist and have had experiences that ghosts seem the most plausible explanation. My photography hobby has even produced some unusual pictures with light, shadows, and rainbows in unexpected places. This includes pictures taken aboard the Delta Queen. But rather than go on record as the believer in ghosts, I prefer to just admit I have a very open mind (things always fall out and in)and if we have any ghosts aboard, they are good ghosts.
Does that help your curiosity or wet it more? Anyway, the charm of the riverboats is much more than whatever ghosts are haunting the rivers.
