I've been reading up on how-to grow your own vegetables, and potato harvesting sounds like the most fun so far. It started with this blog post. Near the end he's talking about his crop results, and then, bam! Constant vigilance! Oh Harry Potter, you show up in the oddest places!
But yeah, basically, I would love to try some of this stuff out. I'm not big on brussels sprouts or cabbage and such, but fresh cucumbers and tomatoes and potatoes would be so cool!
