So, really, what I was doing - I thought briefly about putting some duct tape racing stripes on Cara... but I didn't have enough duct tape. Meanwhile, a branch fell off the tree onto the roof, denting it.
I got it inspected, so it's good till January. (Registration has to match inspection.)
I had a camel ad in the back of my van for like 5 months now, so I just decided to cut it up and duct tape it over this big hole

in the front of my minivan...
Once I figure out that it won't cause my van to overheat, I'll just leave it there until I devise something a little better, like some fiberglass. Of course, if I'm going to do FG, I may just want to close the whole thing in and slowly trim out a port for airflow.
