My little adventurer Lauren went up north to help a friend with the interior remodel of a cabin; floors, walls, ceiling, etc.  In her free time she learned how to use a weed whacker, riding lawn mower, and a rototiller, which I used to incorporate into this year's birthday card for her.  She does everything in her bare feet, which are more leathery on the bottom than most shoes.  If she ran over them with the mower or tiller, I'm sure her feet would do more harm to the machines than they to her feet!!!
