Carrying the emergency blanket seems like a very good idea, has anyone used it for an emergency shade? how good is it?. I am riding in Cancun (southern Mexico) at the moment and the first days the sun has got me nearly exausted to the point I really need to go hide for a few minutes under a tree. I don't know what would have happened to me if I was unable to find one.
Another advice when riding in hot wheather: think of how much water you are going to need, then carry at least two times that! I learnt that the hard way
