The more complicated an idea, the more we like it :)
So, Chris and I have been a little slow with putting together the raised garden bed that we were previously pretty excited about. For one thing, we're now only looking at one bed, and instead of buying a bunch of cedar or spruce boards, we bought a kit with a plastic frame and metal poles for stringing up tomatoes, beans, peas, etc. I realize that this is quite a change from previous plans, but this bed can be disassembled in the fall after the growing season and move across the country with us.
Now that we have the frame, seeds (peas and romaine lettuce), compost, and soil, the only thing that's stopped us from planting already is that we need some sort of liner for the bed. Surely one just doesn't dump the dirt on the lawn, right? Our first thought was to line the bed with some sort of plastic, or maybe even a tarp, but now we're wondering if we don't perhaps need something that would allow drainage ... Maybe a formed plastic liner with some holes in the bottom?

I think this is one of the better step by steps I've seen. They don't recommmend soil just organic material to mix in with existing dirt. It depends on how high your raising it. If you are going over a foot you probably would want some pea gravel as your bottom layer for drainage.
