Robin enjoys lunch in the dining room (at the rear of the ship) as we go through the Gatun Locks. Through the rain covered windows you can barely see another ship following us, one lock behind (right behind Robin's head).
The canal first opened to commercial traffic in 1914. In 1928, Richard Halliburton swam the Canal. It took him ten days and cost 36 cents in tolls (passage fee based on weight, I assume).
