Dog Gone s01e03 - Road Rash
I noticed Ponch has some real road rash on his right forearm, about 4 - 5" long and 2.5 - 3" wide. I figure the stars didn't do anything but the initial take offs and stops in the early episodes. There's a lot of shots of the bikes in motion with their faces cropped out. It makes me wonder if he went down taking riding lessons or learning on his own.
It's interesting to see the various states of healing during the show. It shows that scenes weren't filmed in order during the week as the wound goes back and forth from heavy scabbing to nearly raw.
