It's a surprise to hear that the GB is selling the Boonville KH. Back in 02 and 03 when I was doing research on Joe Rutherford I visited this congregation several times. The local JWs were very friendly and helpful. I didn't tell them that I'd left the JWs in 1984, so they thought I was just another worldly writer.
Anyway there was this elderly JW lady who told me where Rutherford's house was located, his legal office, and other interesting items. Yes, Rutherford's house and law office are still there. This lady's daughter-in-law gave me some leads as to the academy that Rutherford attended after graduating from High School.
Since this was Rutherford's old congregation, and he was the founder of the JWs, one would think that his religious heirs would keep this KH, even if it was justfor the historical and sentimental value.
