Ready-made environments for import?

I used SU about 5 years ago and I recall finding ready made environments like for example Dealey Plaza in Texas. I wish I had stayed with SU but didn’t but now am back to using it. Is there a repository of free files you can download like Dealey Plaza?

Thanks.

It’s called the 3D Warehouse (look on the File menu). I have no idea if Dealey Plaza is there, but you can search for it.

Thanks! I found it and it’s there.
