Commemorating the first 25 years of Geocaching
and looking forward to the next 25 years to come.

Just like the early Oklahoma settlers faced many challenges*, you and your crew will need to rely on keen geo-senses and ensure you have all the necessary tools ready to meet the challenge of finding this series of geocaches and completing the Geoart as you Geocache Across the Plains.
In an Oklahoma city, a teen wrote of greasers and Socs at her desk in high school between lunch and clocks; her publisher feared boys would not buy a girl's book, so they hid her two given names under initials' locks. (One Word)
You can validate your puzzle solution with
certitude.
*We use the Handicaching.com rating code system for 1 T-rated geocaches: H14232 (This is the worst case.) Climbers, ladders, and additional tools will be needed; this is not entirely a PnG series.
