My scrap is made up of leftovers from track work and from kits. Most of it I cut up into smaller pieces, and at one point spread it out in a box and gave it a blast of oxide red spray point, then shook it and repeated a couple times.
Here is a shot of the power on JAMU6 heading west towards Muskegon. I have to get some decent pictures sometime soon, for now I'm just using my phone camera once in a while.
