I'm afraid they went into the water to cool off, because their bikes were found near the lake.  They're draining that lake, so we should know in the next couple days if they're there.  

I've always theorized that Jodi is in a body of water too, possibly just a mile or two north of the Key Apartments. I think she was killed and dumped shortly after she disappeared, perhaps weighted down with some sort of boat anchor.  I wish some of those little ponds could be drained to look for her. 

The Midwestern drought is a terrible thing for the farmers and I hope it ends soon.  However, if it doesn't, maybe the water levels in some of the ponds will fall far enough for Jodi to finally be found, hopefully along with evidence against her abductor.   He's been free far too long.
