Exactly. I was big into astronomy years ago, but realised my hobby had become 'list ticking' rather than enjoying it for the original reasons. The same happened with hunting stones a few years back.
These days I visit a handfull of sites a year and get a *lot* more out of it than the days when I tried to fit in twenty stone circles in a day, racing round with my maps.
It's not about quantity, it's about being there and taking time to drink in the whole thing.
