Weaver, son-in-law of Erling, and his brother Bobby transformed Logan's into a large scale operation. Leonard then passed the company down to two of his sons, Leonard and Mark Weaver who built the company to what it currently represents today. Presently, Mark, and two of his children, work at the company and continually strive to grow larger than ever before.
