Thanks for this, Bob! Lots of memories.
BTW, by the time I met Jerry Baker (and his brother Tom) around 1970, he was still working as a mechanical engineer and running Bakers Bikes from his home on Mercer Island. Later he moved to the U-village area, as well as start his Baleno custom bike clothing/accessories operation instead of Baker's Bikes (he told us Baleno meant "flash" in Italian...). I made a short film about him for a high school project in 1972, and was honored when Spot (his wife) asked for it to be shown at his funeral.
Another PNW framebuilder to mention is Mike O'Brien. I think he started sharing some garage workspace with Glenn Ericksen in the late 80s, making a small number of frames for Gregg's Greenlake and then going alone as a limited custom-only builder. Mike is a family friend for many decades, now retired. I still rotate riding my O'Brien 1990 custom steel, updated with Ultegra 8 speed STI!
