There was one place just inside Oklahoma but just off 66 that we wanted to visit—Picher. This town is the totally condemned because it is the worst toxic waste site in the USA.
Who determines which site is the worst -- I would think that mining town in Colorado might win that one -- No one is allowed within 1/3 mile of the entrance because of the hazards of the soil and such. {Of course, the name escapes me at this moment}...

Happy 4th to you too!
