Seeing dolphins is just so Kewl. However.....back in Kansas when you are driving a car and something runs out in road in front of you (like a squirrel, deer, cat, dog), you....
1. Slam on the brakes - so you don't hit it.
2. Swerve to avoid - so you don't hit it
3. Hit and generally hurt or kill it
As dolphins swim along with us, darting this way and that, my first reaction is...."Oh kewl!" And then immediately I think " Look out! Be careful Mr and or Ms dolphin! I don't want to hit you!" Silly I know but it's just roadkill instinct after all these years.
