Exactly, and the makeshift memorial is just that, and it is beautiful - it's right off the road and its very small footprint doesn't really infringe upon much of the surrounding land. We were there several years ago, and if it is still the way it was, to the right of this photo they have a small parks building with albums you can look through and one parks worker on duty. There are park benches engraved with the names of those who died, carved rocks and memorial stones on the ground, and the wall you see in the photo is fantastic, with notes of thanks like "Thank you for not hitting our school, love, the students of [name of local elementary that is quite close by], and all kinds of firefighter, police and soldier memorabilia.
The memorial's construction was mostly spontaneous and personifies the fierce patriotism of average Americans and I think it should stay just as it is. It is a respectful distance from the actual crash site, which is probably several hundred yards in the distance across a field - in the photo it would be out off to the left.
