I'm glad to know I'm not alone.
It isn't always cheap.
My mother took a grandson on a trip to Churchill Manitoba, Canada to photograph polar bears.
I could get a 5Diii for the price of that trip. Interesting trade-off. Have memories and pictures of Polar Bears on the tundra, taken with a mediocre camera, or have a professional full frame camera sitting in the box at home. Photographing polar bears wins.
