I have downrated the cache to keep it free and accessible to everyone. The actual difficulty level is more like 1.5/2.
No matter which way you approach this cache, plan for a multi-hour hike or mountain bike ride. Bring sturdy shoes, as small cacti abound in the area. In summer, remember to bring water to drink. This is rattlesnake country, so be cautious in warmer months.
You'll be rewarded with nice views, and might see wind turbines rotating in the north, toward Boulder. When you log your find online, tell us which is your favorite Dr. Seuss book, and why. I love reading Oh, The Places You'll Go! to my kids. Whenever I'm standing in a long line, I'm reminded of Seuss' "waiting place."
