I should probably keep these excellent epiphanies to myself, but for the good of all mankind, I am releasing them to the internet:
1) whenever we had to park the van in a hot and sunny spot on our trip, we used a pair of silver windshield shades to block the sun, and they really helped keep the car (especially the steering wheel) cool . . . so why not make shirts, hats, jackets and umbrellas out of this material, so that you can walk around in the hot southwestern sun and not burn up . . . hopefully, some famous fashion-designer will read this and get to work on something that doesn't look too sci-fi/garish;
2) there needs to be a horror movie about a spider-snake . . . some people are scared of spiders and some people are scared of snakes, but everyone is afraid of a spider-snake.
