The minivan ramp drawing reminded me of the day I came home and found 3 of my children jumping a ramp with their bikes in my driveway.
I stopped and watched from the end of the driveway....not too worried as the ramp (heavy cardboard boxes, flattened) was only about 10" high.
I watched, then asked, " where's Katie? " (6 yrs old)
I hollered this from my car window a couple of times....finally ...Katie stuck her arm out and waved from under the ramp. They were using their little sister to hold up the ramp.
That little nut was fearless....
