I know there are several Gunsmoke TV show fans here, but since harvest has/is starting up thought I would post this link to listen to the radio program on your phone Gunsmoke Radio Show (1952-1961) It is on Archive.org which is not the easiest to navigate, but there are many other shows that can be entertaining as well. There are tons of option on the Old Time Radio section  I'm sure there are others but there is plenty here to run me for several more years.In the past I have downloaded some programs form there to manually upload to phone if you don't want to use data/don't have service in the field but it was a bit of a process.

Have fun and be safe out there during harvest,
