This location was once home to the Allison Building, which housed the J.T. Rogers & Co. Drugstore. In the 1870s, a local farmer remarked to pharmacist William Allison that it always seemed to rain on his birthday, July 29. In 1874, Allison began tracking the weather on that date every year, and a Waynesburg tradition was born. The recordkeeping was inherited by Allison's brother, then by the owners of the Daily & Spragg drugstore, Byron Daily and Carl Spragg. The records were taken over by Daily's son, John, who "bet his hat" with a national or regional celebrity that it would rain. The late newsman John O'Hara helped Rain Day grow to national prominence.
