Ghost cars on HO layouts?
I am building a 4 lane 4' x 16' replica of the Daytona road course but racers are hard to come by where I live. I still like the look of multiple cars running all at once though, even if I'm technically not "racing" against them. What I want to try is to have at least one ghost car per lane (that I'm not in), and maybe even try 2 cars in some of the lanes if I can find cars that are evenly enough matched that they do not "catch" the other car in the same lane.
Anyone else ever try this for fun? Did it work? Thoughts or ideas? Thanks in advance.
