The possum living link was pretty interesting. I'm a bit more addicted to my creature comforts than those folks seem to be, and not so sold on abandoning the luxury of money. Their take on the law is pretty unique

I wonder how it would fly these days, vs. in the 70's?
Sunroom/greenhouse - Still very much in the planning stages, but what I've got so far is something attached to the house, lean to fashion, and functioning as a passive solar design. I'm thinking of doing a recycled red brick wall on the side that abuts the house as well as a brick floor (over a slab) it would be vented into the house to take advantage of the solar heating, and well insulated. I'd like to use as many recyclable materials as possible ( I can find double glazed used sliding patio doors here for ten bucks, for instance) but am in the process of hunting down local code so I can design it in such a way that it won't detract from the value of the house. I still need to figure out how to vent it in the summer. I might rig up some way to shade the glass to help cut temperature. I want to put a rectangular fish tank at one end. Probably made from masonry with some sort of liner or waterproofing. I haven't really gotten that far yet. I'd probably plumb it, to facilitate draining and filling, and i want to make it look nice enough that we can put some water plants in it when were ready to sell and call it an indoor pond. I haven't found a whole lot of info. on very small scale aquaculture, but I'm still hunting. Tiapia seem to show promise, but there's no way I could keep an outdoor aquaculture tank operational for their growing season in southern Wisconsin.
The rabbits are in the basement largely for the same reason the possum folks keep theirs there. It's easier for me to tend them. They are in commercial wire cages and have full spectrum lighting and an air filter running for ventilation. I'd rather that as few people know about them as possible. I could probably get away with having them outdoors, but between the winters, the dogs, and the possible neighbor hassle, I'd rather not. I would like to play around with rabbit tractors in the warmer months, and might give that a whirl, one of these days.
The wife is interested in blueberries and blackberries, but we both work full time, so it's slow going with new additions. She's also starting school in the summer for a nursing degree on top of her full time job. Between that and our daughter, and our menagerie, we are pretty busy most of the time.
Interplanting is a great idea. Our rasberries are mixed into a long bed of perrenials on our back fence. The only other existing decorative plant bed we have is in the process of being redone. The previous owners threw down about afoot of gravel, plastic, then another six inches of gravel. All this surrounded some pretty monstrous evergreen shrubs that we cut down right after we moved in. Found the gas meter and a basement window in the process

We're probably going to grow tomatoes there. We had problems last year due to the neighbors black walnut trees rooting into our garden space, and the new bed is much farther away. Everything but the tomatoes seemed to do Ok with the walnut toxin.
I'm a little concerned that if we do too much here, I won't want to leave

I guess I'll have to see where we end up in a few years.
