Bob's Boars and Carl's Corn is the same building. It's a large house with those two slogans on signs out front, with raised garden beds of corn in the front, and a retaining pen in the back surrounded by fence. I tracked down a video for anyone curious. You have to watch it a bit through to see what the outside looks like, for some reason this particular gamer didn't start recording until he'd made it into the middle of the building and harvested everything.
