To search by different types of Hosts, you can use filters
On the Website:
First, you can go directly to different states or search along a route. You will see the red bar that says " Preferences." You can select the type of Hosts you would like to see. You will only be able to see "Golf" and "Boondockers Welcome" if you are subscribed to those options.
On the App
Click on the filter button:
You will then be able to see the different categories.
