When it came time to load the van back up at the end of the day, however we were puzzled to find that it wouldn't all fit. We pulled crates out and moved them around, but no luck. Tried again. Eventually we got everything in, with Caitlin still stuck with a pile of things in her lap.
We still don't really understand the physics of this problem, but we've heard that it happens to other farmers, too. Next week we may have to take a second vehicle down to ensure that everything makes it home.
