Ever since the highway went through our backyard, I've hated the big wall / sound barrier back there. Here's a pic http://i172.photobucket.com/albums/w16/ClassyDame009/backyard001.jpg

I want to grow a vine to cover it up. I live in wisconsin, borderline zones 4 and 5. The side of the wall we have to look at doesnt get much direct sunlight. The soil around here has a lot of clay in it. I don't know much about planting vines, so I've been reading up on the internet. So far, I'm leaning towards Boston Ivy, but I read that it attracts a lot of bees. I have a 3-yr old, so that worries me.

With the other types of vines I read about, it sounds like so many of them are pretty aggressive. While I don't care if they take over the pine trees (the city planted those...a sad attempt to hide the wall), I'd hate to jeapordize our other tree back there.

If anyone has any suggestions or advice, it would be much appreciated. Or if anyone has experience with Boston Ivy, could u tell me just how bad the bee issue is? Or any tricks for keeping the bees in check?
