If so, then Dad was lying to us. Because in his most recent interview he says that he promised he would return at 11 to give Dylan a ride, and that Dylan acknowledged everything he said.
If that is true, and Dylan thought his Dad was returning at 11, then I don't see why he would try and hitch a 20 mile ride. Especially without even speaking to his friends that morning.
I think I'd believe Dad's version rather than the speculation of someone who wasn't anywhere near there. I think people need to keep the few things we've been told and try to fill in the blanks, rather than changing the little we "know" to fit their ideas.
Just want to add that I know you weren't doing this katydid, but at this point people shouldn't even be putting that out there as an option. MOO
