If you have a cellphone with data, you could enable Google Timeline which is compatible with Android iPhone/iPad and computers.
Once enabled it will track and record all your movements which then you can view in google maps (you can even receive a monthly report if you want). The issue is that the state lines when you are zoomed in are so faint that is hard to see them, but on the other hand, you can download your timeline data as a KML file (and other formats) which can be opened in google earth which can show clearer borders.
Here is an example of some data I collected from my phone, the red dots are stops I made:

Hope this helps.
