Hey pd...
I know the importance of drinking water BEFORE I feel thirsty, and make a point of it every day, but particularly when out riding as I don't want to get dehydrated! The only time I've experienced it was while riding through the Badlands on a day well over 100 degrees, and no water-stops readily available. I never reached the point of disorientation, but I sure did desperately feel the need to cool down and DRINK!!!!!
I would think that any wisdom you could share that would promote safety and happy riding would be welcomed. How, in particular, were you thinking of using your information? Your question almost sounds as though you have a business idea in mind.
