Thing is, the projection is 360 degrees, so it really is just a small clearing in a forest, or if you look at the link I posted, you see photo's under a bridge, or in a room etc. It is not so much to do with the scale of things. Your camera is the middle of that panorama.
So you'll need a large clearing in a forest for this to work, if you follow what I mean.
There are some sky panoramas with some forest on the horizon, though.
If you are looking for some stuff to reflect in glass, you can also put something behind the camera on a curved surface to fake it.
