Yet another spherical pano

This is the Park Ridge East spherical "small world" pano stitched from 66 individual photographs using Adobe CS5.  I am impressed at how well it actually handled the data and the speed.  I had tried to stitch this one earlier using both Photoshop (CS4) and Hugin, but with no success.  The final size of the image was 6000 x 6000 pixels--this one is reduced for faster loading so you can't see all the detail.
