The Royal Canal has been disused and derelict for over half a century and it has now been painstakingly restored. Dick Warner is going to travel on it by barge from from the Liffey to the Shannon. It was 1992 when he first did something like this - travelling from the Liffey to the Shannon on the Grand Canal. Between then and now economic boom and bust has totally transformed Dublin's docklands. Why is he doing this? Because the passing years have failed to quench his thirst for exploration. Unexplored territory doesn't exist any more - but it's not necessary for exploration. And so he joins his boat, which is called Rambler, and is owned and crewed by members of the Connon family - John Junior, Evan and Johnnie Senior.
