A simple counting mystery cache that can be done from your vehicle and that most vehicles shouldn't have a problem driving to. If you aren't comfortable driving this road, it is just a short hike from either starting point. Bring Your Own Pen.
Congrats to billkat for FTF!
From Stage 1, just off Purcell, N38 20.450 W104 41.860, either drive or hike southeast down the dirt/gravel road. Start counting manholes as you go. They are very noticeable and just a few feet from the road on either side of it. Count until you get to #6. Stop directly by it and go up the small hill. The cache is south of the utility box, under a small bush at the crest of the small hill.
From Stage 2, just off Sapinero, N38 20.158 W104 41.476, either drive or hike northwest down the dirt/gravel road. Start counting manholes as you go. They are very noticeable and just a few feet from the road on either side of it. Count until you get to #5. Stop directly by it and go up the small hill. The cache is south of the utility box, under a small bush at the crest of the small hill.
After completing this cache from either direction, don't worry about making a U-Turn. The road goes the same distance out as the distance you came in and will get you back to a main road. If you need back to Purcell, when the road returns to a paved road make a right turn. The next street is Purcell. If you need back to Sapinero, when the road returns to a paved road make a left turn. Watch on your left for Sapinero.
Please use caution for slithers and critters and after any rain or moisture.
This is a great place to watch for wildlife and we did see a huge owl sitting in a tree on our way out after placing this cache.

Please make sure cache is secure before leaving. The rocks will keep it from washing down the hillside or blowing away. It is also attached to the bush with a wire. Make sure this is still attached.
