I came across this clever bit of track naming while cross-country skiing today. After a rather challenging hill climb on the Cardiac Arrest, the trail forks. You can choose the Defibrillator and enjoy a nice cruise downhill. Or you can continue on with your heart-stopping trek.
I find this sort of subtle humor highly enjoyable and would like to give the track layer a hearty back pat. Except I have no idea who that would be.
