Got this cool little wired GPS tracker on a lightning deal on amazon for $21. monthly plan is only $6/ month. I have not thought through how I am going to power it but I can deal with that later. There are a ton of these types of trackers nowadays. https://www.amazon.com/dp/B07KDZ57HC?psc=1&ref=ppx_yo2ov_dt_b_product_details
