In the early 1990's, inspired by Joe McMillan's "High Green To Marceline" and the rebirth of the warbonnet, my buddies and I railfanned as many of the photo locations on SF's east end as possible, like the overpass at Argyle, IA. It was a good spot to bag the 199 in summer light, this time yielding an A-B-B-A lashup.
