A flooded bog and a barn. To do a wet harvest, growers flood their bogs and then use machines that look like small paddle boats to knock the submerged berries off the vines. The berries float to the the surface, where they are corralled and then pumped out of the bog and into waiting trucks.
Here are some typical sites you'd see driving around Carver: bog after bog after bog and signs for Ocean Spray-affiliated cranberry growers.
When we got to the Cranberry Harvest Festival, we took a school bus shuttle from the parking lot, through the woods, around the bogs, and to the festival grounds. I got to take only a couple pictures before my camera died...for good. (Argh!!!) Here's a pic of Mumma with a flooded, berry-rich bog in the background and a pic of some berries floating in a bog. Unfortunately, these were the only pics I was able to snap at the festival itself. If you'd like to see how a wet harvest works, check out this video of a cranberry harvest in Nantucket. It's not Carver, but you get the idea.
