Ultimately this challenge started with my very first cache found near my home (at the time) in Harris County, TX on 2010May22.

This challenge ended with finding a cache on the courthouse grounds of Hopkins County on 21Jan2019.  I was excited to finish the challenge by signing the challenge log book on my birthday, 28Jan2019 at the top of Mt Bonnell in Austin, TX.

More later!
