I was thinking.....Pops proved to be a good rendezvous point. We could meet there at 01:00PM again, drive east to somewhere else famous along 66 at 01:30, and eat. Then when we are done, we all go back to Tulsa/OKC. This idea hinges on finding another cool place along 66, which I have not been able to find.

I will be driving from Tulsa to Edmond tonight, and Edmond to Tulsa tomorrow, so I will have my eyes peeled for any other eastward interesting place.

I found this site, which mentions some roads less traveled in Oklahoma.
