According to the calendar, we still have a few more weeks until summer is officially over; but for most people, Labor Day weekend marks the spiritual end of the season (and the beginning of one filled with cold, vitamin D deficiency, and slipping-on-ice concussions).
Some people will use this remaining time to scramble to do the things they said they'd SWEAR they'd do next weekend every single weekend this summer -- namely, something other than drinking their weight in beer and falling asleep in front of the A.C. with their hands covered in cream cheese.
I'm sure more than a few people will spend their weekend doing everything they can to maximize their tan before the sun is no longer strong enough to drastically increase their risk of contracting melanoma.
But at this point, there's really only so much you can do to make up for months of sun exposure.
By now, most people have already earned a fairly defined set of tan lines, and it's pretty easy to figure out how they spent their summer if you know what to look for.
