1. Wind Chill

So maybe the magic "zero number" is 98.6 - the temperature of a human body. If the air is cooler than 98.6 then the body is cooled. The lower you get from 98.6, the more cooling effect. If the air is hotter than 98.6 the body is heated. If the air is exactly 98.6, you feel no change, no matter how fast you drive. So if you graphed it, it would produce a bell curve with the peak at 98.6 degrees. This make sense to me.
2. Wind Chill

So I ran across this wind chill chart geared towards motorcycle riders: http://3.bp.blogspot.com/-HrbLdfclw8U/TbIcYRsqC2I/AAAAAAAAAZQ/UrNjSInoXts/s1600/motorcycle+wind+chill+chart.jpg Studying that chart, I notice that the faster you drive, the lower the temperature feels. All as expected. Then I notice that the hotter it gets, driving faster feels less cool. For example, at a 50-degree air temp and at 30 mph, the wind chill drops the felt temp to 28, a decrease of 22 degrees. But at 90 degree air temp and that same 30 mph, it only drops the felt temp by a 1 degree to 89. Hmm. Okay... And then it gets really weird. At 95 and 100 mph, this chart claims that anything above 5 mph actually makes you feel HOTTER, rather than cooler. Now I'm skeptical. How can that be? I wouldn't think it possible for the wind chill temperature to get higher than the actual temperature. So driving fast on a really hot day through the desert isn't going to make you feel any cooler? At least not temperature-wise, according to this chart. But of course, driving fast on a motorcycle makes you "cool" in another sense. Can any of you thermodynamic geniuses out there explain this?
3. Did you invest in GoPro?

Headline: "GoPro Is Getting Creamed" Link: http://finance.yahoo.com/news/gopro-getting-creamed-175037526.html I don't understand this part: "the patent specifically mentions the weaknesses of the GoPro devices. Specifically, the patent notes that the new camera system could be secured to various objects, such as a bike helmet or scuba mask, or mounted to the handlebars of a motorcycle or the front of a surfboard..." That's not a GoPro weakness - that's why they're so popular, because you CAN do that. Can anyone explain?
4. How big of a volume difference in regards to packing skills ?

Yep. I see many new guys who seem to think the goal is to make the cocooned canopy as skinny as possible. And then it piles up so thick right in the middle, that they have trouble getting the container closed. I cocoon my canopy WIDER than the bag by a little bit. That spreads things out as much as possible inside the bag, and makes the ends as firm as the middle. Then no trouble closing the flaps.
5. Would you rather be able to fly, or be invisible?

So how do his results from the general population compare to the results here from skydivers? I'd expect skydivers to lean more heavily towards "flight" than the average whuffo. But then, whuffos not having experienced freefall the way skydivers have, maybe they would value flight even more highly?

7. New Rigging Tool

Very creative use of a socket wrench! Now figure out how to attach a scale showing foot pounds of torque applied.
8. Would you rather be able to fly, or be invisible?

You would need an invisible Gopro camera too.
9. Would you rather be able to fly, or be invisible?

Invisibility would be far, far far far far far more profitable. I could see robbing banks. But it would be nice to be invisible and stay legal. How do you make money legally with invisibility?
10. Would you rather be able to fly, or be invisible?

Would you rather be able to fly, or be invisible?

What's that?

boobies!
13. Pinholes in Canopy Tail?

Has the canopy draped over a barbed wire fence? Landed in a briar patch? Jumped in Florida where the landing area is full of sand spurs?
