One of the coolest back to nature phenomenon I've seen recently is goatscaping. Instead of hiring someone with gas guzzling equipment to come clear your land, there are companies that will now rent you goats to clear the brush for you. It's eco friendly, thorough and goats!! I happen to think they are one of the cooler domestic critters around and I admit I'm tempted to get some to clear up our back woods just because I want to be able to watch them amble about. We've actually even looked into the possibility of getting a pet goat, which could double as a lawn mower, though they seem like a lot more work than cats or dogs...I think we're much more likely to just get a hedgehog.
