After she begged and pleaded, I bought Harper this hot pink convertible (knock-off brand) Hot Wheels a couple months ago at Goodwill. It semi sucks.
The thing gets stuck on any and everything and she just can't get a good run out of it. And she's tried. But then, after a joint branch clean-up session around the yard (give a toddler "work" and they will go nuts) I decided to move the car to a new locale. And wee! Hilarity ensues.
