Thanks for all the sympathy on the sunburn and suggestions. I can handle the pain but what really upsets me is that I stayed in the shade (under an rented umbrella) except when I was in the water. Each time I went in the water, I put on lots of "waterproof" 55 SPF sunblock. I guess I just need to buy a UV protection rash guard to wear at the beach. Oh well, enough complaining.
Got the Pico Slim and DAC from Bryan!
