According to the newsletter the club’s 2019 ride challenge is “Historic Markers”. The only rules I can find are:
- The challenged started March 1, 2019.
- The participant needs to find 10 Historical Markers in one State.
- “Markers must be official signs that state the historical significance of the site.
I email Bill Brown to what is considered a historic marker. His response was a marker that describes the history of the spot. I interpreted that to mean any historic marker.
