When Gilligan's Island first came out, I remember my family and I exclaiming whenever we saw Alan Hale Jr. appear on the screen, "Hey, it's Casey Jones!" I truthfully don't remember much about the series, as I was but a tyke when I watched it, other than seeing Alan Hale Jr's friendly, smiling face looking out from the train as the opening credits rolled. I remember liking the show and our family sitting around the t.v. enjoying Hale's characterization of the legendary engineer. I enjoyed the other comments and remember it as good, wholesome family entertainment.
When I was in my twenties and living in Los Angeles at the time, I took my fiancé (now, wife) to visit Alan Hale Jr's Fish and Chips Restaurant in Glendale. Hale just seemed like a very happy and likable fellow as well as a great character actor.
