Thanks to all who responded. I will definitely work toward a grub-free lawn; the total property is over 2 acres and partly wooded, so I'll just focus on the open areas, definitely using organic solutions.
The yard is very wet (per one of the responses indicating that will rust the hardware cloth quickly); I think with proper placement I can avoid the garden area itself being too wet. The biggest reasons I wasn't looking at raised beds is (a) I want to avoid all treated lumber, but haven't found anything that is affordable as a good alternative that will last as long, and (b) for the vegetable area of the garden I want to be able to use my larger tiller to add compost every other year, and (c) the garden will have a temporary greenhouse on top because the winters get just a little too cold, and all the greenhouse books give a range of options, from freestanding pots (which lose a lot of heat quickly due to large surface area) to larger raised beds (medium heat loss) to what they say is the best option- planting directly in the ground for maximum heat retention (I'm actually considering putting in some subsoil drain pipe and a fan to capture heat in the soil during the spring/fall- cheap if I do all the labor myself).
I'm new to the area (Pacific Northwest), but all the neighbors say not to let the cat out (or any dog under 40 lbs) due to the coyote population and the eagles, which have a reputation for taking small domestic animals (there goes my idea of getting a chihuahua to rat out the moles).
Again, thank you all for your suggestions, and I'll continue to monitor for additional replys, questions, or suggestions.
Best, Keith
