is there a way to turn on the state lines so I can find locations near a state border.

There is an option in BaseCamp to determine what is displayed but unless you've fiddled with it in the past everything is on by default so if state lines aren't showing then they aren't on the map.

I am looking for campgrounds near the California state line. I do not like to travel in California and am looking  for campgrounds east of the California state line. Is there a way to turn on the state lines in basecamp?

State lines are considered "Political boundaries" in BaseCamp so go into whatever profile you use and look in the "Lines" section of the "Map Display Features".

Should be enabled by default as I said earlier.  If it is state lines should show, they do on mine.

Understood, but if the settings are not at default, knowing which option controls state lines may be of value.

Certainly
