I’m re-reading his book for probably the 5th time. If you haven’t read it it’s a definite must. He mentions the Blue Ridge HT in VA and there are pics of it. Does anyone know where this was held?
I may be able to get you a more specific address with more research, but it was near Millwood, Clarke County, in northern Virginia (but a bit west of what is usually considered “Northern Virginia”).
I know that Trish Gilbert’s family was involved in running it, and it may have been on their farm.
I competed there quite a few times, before it closed down - not sure what year, but it was still running in 1997.
Here is an article about the 1960 running
