Ever since we got that new system a few years ago, it has been consistently mistreated and caked with dirt and grime at the offroad track. The system is only 2 years old but it looks like it's 20 years old.

At one point last year Bob Stellflue helped me rewire part of it that had been ripped off; I'm not sure if that is the same issue but I do think I know what you're talking about.
