Sorry for the loss. I too have seen posted material of Al's work. p51 has a point. Born in 60 I find people older than myself still very enthusiastic about Model Railroading. Starts when we are young takes hold and stays with us. While at a Narrow Gauge Symposium in Houston years ago I found out from Al Roos that a Modeler I admired very much Bob Clarke, had past away. I had no idea till then. I still have the issue of MR showcasing his HOn3 version of the Ironhead Timber layout. Great people in a fine Hobby. God's speed Al.
