Josh gave me the Big Box O’ Tires last week at ICF, but I haven’t had a chance to dig through and play around with what’s in there just yet. I do think there are enough to make walls along the track in some fashion. Although that typically happens on curves, which we apparently don’t have on this course. 😉
I might be able to chip in on some other aspect. Do you want to add the Goodyear blimp to the Doodle? Or any other tangential details that might help fill vertical space or something?
