The lines are quite comical. I'll start with the mildest and work my way up.
Exhibit A: above the knee. My legs now have two tan lines - one where my running shorts hit and one (slightly more crimson) where my pants pushed up to on the golf course.

Exhibits B & C: shoulders and neckline. I now am sporting a beautiful stripe down the inside of both arms and a tasteful red v-neck. Too bad my star necklace didn't stay place long enough to make a lasting impression.
Exhibit D: coon eyes. I mentioned putting on my sunglasses early in the day. As I felt my forehead burning, The thought of coon eyes crossed my mind, but I seriously underestimated the power of UV-A & B. Now I look somewhat akin to what I imagine Rocky Raccoon would have looked like, had the Beatles done a video (only prettier, and with blonde hair).
AND last, but not least (my favorite) Exhibit E: the Zong. Years ago, I had a few friends who lifeguarded during the summer and the season was validated once the imprint of their Chacos was left on their feet. I managed to validate my summer in just one day on the golf course.
Despite what one may think, I had a relatively good time today. And, even though I may have multi-colored extremities, I'm thinking of taking up the sport.
