I do sunbathe alot, and I know they've all seen me laying out in bikinis, but I've done a few things where some may have seen more of me than should have.
Somtimes when I lay out, I'll turn my chaise lounger so my feet are towards the road. My legs spread a little too far apart, pretend to read, and count how many cars slow down. Not a high traffic area, and I have not done it in a while, but record 7. Maybe if my building were closer to the road, I'd have hit double digits.
