This was left at my "State County vs. State DeLorme Challenges" https://coord.info/GC7RDQZ event so I'm rescuing it.
My brother an I will be taking a trip to New Mexico in September of 2019. We make an annual trip to a different state to take a tour of it and complete various goals including the oldest cache in the state, the cache across America cache, the county challenge and the Delorme Challenge. I'll drop in New Mexico's oldest next September.
If the owner wants me to place it in a cache sooner, I can do that too.
