http://www.mob-rule.com/ allows a user to track the US counties they have traveled to and produces a nice map of the results.

I have a traveling goal of crossing all the US state land borders. For example, to complete the state of Idaho, I would need to cross the WA/ID, OR/ID, NV/ID, UT/ID, WY/ID, and MT/ID borders. Is there something similar to the link above for tracking the state lines that someone has crossed? Ideally it would in some way "color in" a border once you've logged that you've crossed it.

    Never heard of anything like it, but it sounds like a nice weekend project for a developer. Commented Jul 15, 2020 at 4:50

    You could use a paper map and a sharpie and plaster the result to a wall at your home?

    As a former GIS professional (does that make me a GIS amateur?), I've now decided to do this for myself. For interest I posted your question in the Geographic Information Systems Stack Exchange chat

    There's probably a fun graph theory question in here too. Commented Jul 16, 2020 at 3:02

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.
