Kutler, thank you for that photo. I may be persuaded to do something like that. The only road I knew of that used the SF yellow bonnet scheme was the LAJ. I wonder if there are even more. And thanks for the info too. I'm still leaning towards car cards, but agree that sorting them and all will be somewhat of a hassle. Nomad was using some software to develop his switch lists, I haven't really looked into that, but it sounds intriguing and I may try that. Nomad, any info on this?
