Glen already is, Isaac is, but just doesn't know it yet... Glen was with me when I grabbed those shots on the Hi-Line this week. In fact, he was on my shoulders! You know how hard it is to steady a camera to shoot, with a 3-year-old on your shoulders, wiggling about? And I was using a tripod!
As the Bible says, "Raise a child in the way he should go, and when he grows, he will not stray from it". I'm not so sure, but I think it also applies to railfans....... That pic shows your true wealth (not all of it, though- the missus isn't in the picture).
Congrats! Not only do you have another railfan in your family but I'm sure he will be a Grande fan like his dad. Ben
