The pace is anything but even. The early decades pass in near silence; the filings cluster heavily in recent years, peaking in 2002.

Read together — 23% enforcement, 54 years of accumulation, a parcel of Kings — these scattered records compose a portrait of the address that no single page sets out to draw.
