Trying to contact the site owner/operator to submit some photos of a marker for the Butterfield Stage between what I believe to be Smith’s Station and the next stop. It is a spring where the coaches would stop to water their horses. Please contact me by email. Thank you!
My son gifted me with a replica stage coach 18hx28L I work for the post office. I would appreciate any info you might have on this beautiful item.
