If you are around some place for a long time you miss the changes.

Worked with a Habitat Manager who insisted that the habitat in a rapidly urbanizing county had not degraded over his decades there. Yeah.

I moved away from Sacramento in '72, returning only for visits and holidays. In the early 00s my Dad and his wife drove to Folsom for dinner. On the way we passed a field that was packed with 10-20' tall oaks. It dawned on me that when I left, that was a grassy field. Yes had I driven past it daily for those 30 years I likely would not have detected the change.

Moved to Olympia in '80 and commted from Lacey to downtown daily. Those Doug-firs along I-5 haven't grown a bit in the 45 years I've been here.

You see something every day and don't notice the change.
