Am I Crazy?

I realize this is the second time in a week I'm asking "Am I wrong...", but I had some hamburger I needed to cook and I got home late, so I grilled at 8:30pm.  By flashlight. 

A few friends thought that was borderline ridiculous and I was advised that if you have to use a flashlight, it's probably too late to grill.

What do you say?  Is there a time when it's too late to fire up the grill?  Do you enjoy the "added challenge" of cooking in the dark?
