You can get your fishing license at Larry & Judy’s house. This is on the north end of town (north of Pole’s Place Motel) just to the right of the small red fire hydrant.
You should see a shed as indicated in the picture. The house on this property is where the fishing license can be bought. This is a private residence.
This isn’t Pole’s Place Motel & Gift Shop (pic bottom right).
There will be a gate and the gate will likely be open. (see pic at top right)
