You are wrong Bucky, but thats your opinion and you are welcome to it. I guess if the sun is shining on you and there is a shade tree near you, by your way of thinking you would be cooler in the sun.
I choose to keep covered and cool myself. And I realize you ain't on the coast and fishing off shore or near shore but if you were you would be wearing long sleeves.
In these parts you can tell the visitors in a boat from the folks that fish a lot by what they are wearing. I always shake my head at a guy burning up in a t-shirt in the sun.
Burn on.... And believe what you want. But keeping that sun off is cooler that letting it burn you up.
