I was participating in a discussion in the Vegetable Chat Room about sweet potatoes when reminded I hadn't told you about my sweet potato heritage.
My grandfather H.B. Howard an later his son H.B. Junior (Shorty)ran a large sweet potato operation in East Texas. I worked for them one summer while in Junior High. My job was loading trucks with crates of potatoes. Beach sand soils, 100 degrees and humid. My career in farming didn't last long. Here's one of the actual labels that was used.
My grandfather also invented the potato digger, which unfortunately wasn't a big financial success. I'll dig out some of the press reports and photos on his device later.
