If you are under the canopy it wouldn't be too bad in the rain. I forgot to mention it in the post, but I was actually impressed by the trees they had planted throughout the lawn area. I think in 20 to 30 years it's going to make huge difference. They are going to have a heck of a time keeping kids and idiots from climbing in them though. If the drunks stumbling up the hill don't break them first. I saw so many people grabbing the saplings to stabilize themselves on their way up or down.
