This is my foot.
With the socks and shoes I typically wear in summertime.
But I have this odd tan.
The tan line goes way further down past my ankle than my shoes and socks. It’s a science tan. Because the reason I have this is because about once a month, I do this:
I’m on the beach at South Padre Island, looking for the elusive Lepidopa benedicti. And when I do, I wear these:
Because I can’t shovel in bare feet. Even though I use sunscreen regularly when digging, and even though I’m only there about once a month, it leaves that reminder.
Any other researcher have unusual tans or other distinctive marks they get in the course of doing their science?
(Incidentally, it is harder to get a good picture of your foot than you might think.)
