There are Orcas in the water near Seattle. I lived on an offshore island, took the ferry to town now and then. Whenever Orcas were sighted, the pilot slowed down considerably so they didn’t get hurt. We all rushed to the railing in hopes of seeing them. Almost everyone liked Orcas. Except one old grouch I knew.
