Warning: Bright Sunshine Ahead

Besides its natural beauty, the best thing I like about the Colorado Rockies is its attitude. It's like a gentle giant. Maybe it's the sunshine, so much of it, almost all the time. You find yourself smiling a lot. Last week I was driving the Interstate down the mountains toward Denver, smiling, passing old mining towns with cute names like: Silver Plume, Downieville, Idaho Springs, when I came across an unusual (to me) message on a huge LED sign. The streaming text read:
Bright Sunshine Ahead.

I know it's a warning, but it gave me a chuckle. I couldn't snap a photo of it so here's an example of the type of sign I'm talking about. Usually it throws out an air of dead serious importance. Amber Alert. Nuclear Holocaust Ahead. Not, Don your sunglasses it's a little bright today. Another sign warns:
Truckers. Don't be fooled. Steep grade next 6 miles.
A little cheeky for DOT standards I think. It it makes you wonder about the seriousness of other signage. Like the one that reads:
Retract Your Sunroofs. Falling Rocks Ahead.
No, that's me joshing you.
But since the conformance to standards seems to be getting more casual by the day it should seem no surprise that whomever is programming these LED messages feels free to take a little creative license. The next image I found online is a joke...or maybe not. It's probably sited on a street corner in San Francisco.
