I'm still involved via umpiring although not where my boys grew up, but as for following it's waned tremendously... For the first couple of years, beyond my own boys I'd keep up with their HS/Travel teammates in their college careers (at least from a distance)... Once they all graduated those schools, it was primarily only checking in every once and while to see how my sons' former college teams were doing. It goes away, you develop other interests or rekindle those that you didn't have time for while following so closely. Crazy thing is they grow up too - trust me when they have kids, that will grab your attention like nothing else.
