This is a GREAT topic. For years sunscreen was one of the essentials that I was constantly forgetting. The first time I went hiking around Mt. Baldy in the snow, I remembered my sunscreen, but I didn't remember to put anything on my lips. I got burned from both the top, and from underneath, so badly that my lips cracked and swelled to the point that I could barely talk for a couple of days. It was brutal.
Don't forget your sunscreen, and DON'T FORGET YOUR LIPS!
And congrats on kicking cancer to the curb, quillansculpture!
