Donald, that is a great scene you posed them in, I too would love to see more of your layout, please do post some more shots of it. I really love those SF units, the SF is my 2nd favorite road, SP is my first. Been an SP fan for as long as I can remember but the SF comes a very close 2nd, sometimes I think its really a tie between the two.
Thanks for sharing and i hope you can find the cars your looking for. I have 6 of the Lionel 18" Sunset Limited cars and they are beautiful, I'm with you, I don't really care for the 21" cars, they just seem to long to me.
Everyone have a great weekend.
