That roof is gone!

Yesterday was a windows down kind of day, hurray!
While heading down the road, Chase observed that lots of other vehicles had their windows down too. 
"Look!  Everyone has their windows down today!" 
We were stopped at an intersection  and with much excitement and astonishment he said, "Mom, look at that car, it has its roof off!!!"
Ya, I'm pretty sure that was the first time Chase saw a convertible. 
The fascinating conversation that ensued was quite comical. He likes to know every detail in the mechanical workings of things, just like his daddy.
