Usery Mountain Regional Park since Spencer introduced me to the Geocaching quest last April. Finally, when BJ got home from her Green River trips, the weather had cooled off enough to make it worth giving the 4 mile long, 27 cache UMRP series a shot. We started early with a heavy overcast and a chance of rain.
Even if you're a newcomer to the park, it's pretty hard to get lost. Pilot trainees from local airports during WWII built the Phoenix directional sign, and it's visible from pretty much everywhere in the park.
There's still 12 other traditional caches in the park that I haven't found, so we'll be back!
