Turns out I did learn a few things from the conversations this post, and the Apple discussion board post, that I created. But, nothing that came through those channels provided me with the solution I needed.
But I lucked out! I was digging through some old backups and I found that I backed up my photo library just before switching to Aperture on February 12th of this year. All I needed to do was open the backup, import any photos I took since that day, and move some libraries around and poof! I'm back in iPhoto and loving it.
As I stated, and before anyone gets a little woozy about using Aperture for their photo cataloging needs, the only reasons I am switching back are mentioned in this post. Nothing more. I really like Aperture but I can not deal with those two caveats (unfortunately). I look forward to giving Aperture, or perhaps Lightroom, another look in the future.
