Chupy 4 is a multi-cache format geocache.
The instructions below will get you to the starting point, where you can obtain the first clue to finding the next cache (a so-called "waypoint cache"). You repeat this technique, following the instructions hidden at each waypoint cache, to ultimately locate the final cache. Chupy 4 has 16 distinct steps to complete the full trip, so be prepared for a walk. Allot yourself a few hours to complete this trek. I'd say three to four hours, depending on how fast of a hiker you are and how good you are at entering new coordinates and finding them. It's about 5-6 miles all told. There is NO artificial light anywhere nearby, so if you go near dusk, I'd bring a flashlight with you; you will need it. A sandwich and a BIG, FULL water bottle would be a good idea also, and one of the waypoint caches recommends a good picnic spot anyhow.
This trip is not for the faint-hearted, and I wouldn't recommend it for young children. Teens or pre-teens that have been hiking and don't mind a walk should be okay. There are several steep trails with loose dirt and/or rocks, a few scree inclines, some bushwhacking, a lot of up and down, and more. Dogs are okay in all parts of this trip, but must be leashed during several steps (as indicated by signs). I wouldn't recommend it for horses, but a mountain bike might be okay if you're prepared to walk parts of the trip. Make sure your GPS unit has enough battery power to last three to four hours. Because of the bushwhacking and bugs, I recommend wearing long pants and/or gaitors if you have them.
YOU WILL NEED A COMPASS. You also need to know how to take magnetic bearings. You CANNOT complete this trip without a compass, although only a few steps require the use of it, and the compass built in to your GPS is NOT sufficient. Your compass should have at least a two-degree minimum accuracy, and remember that I will be giving MAGNETIC bearings, so be sure to reset your declination indicators to zero before making this trip (otherwise you'll be 13 degrees off each time). If you don't know how to take magnetic bearings, feel free to ask me for help -- it's easy and I'd be happy to tell you how to do it. I may even put up something on my website (http://www.fatcity.com/geocaches) about this in the future -- check there too.
Since this is a multi-waypoint cache, I recommend that you use the "route" feature of your GPS unit. Turn it on when you start the trip and mark each newly found cache as a new waypoint. This way, if you get lost or want to abandon the trip, you can use the "reverse route" function to backtrack, or use the "go directly to start" feature to take you back to the starting point. Because this trip is not the same as simply going to a cache and then returning to your starting point, but instead takes you all over the area, I am going to categorize this cache as difficult. My directions will ultimately take you back to your original starting point, in case you're worried about that. I wouldn't recommend this trip for a novice, but those of you who have been caching for a while should find it challenging and fun. I'm planning more multi-waypoint caches in the future, so comments would be nice if you feel up to it. This one has been several months in research, planning and setup. Feedback is desired.
How to get to the starting point:
As you are standing at the end of a dirt road at N 32.56.318, W 117.10.251, and facing as if you were going to continue walking up the road and into the brush, there is a small, faint trail ahead of you and slightly to your left. Take that trail to N 32.56.301, W 117.10.262. The first waypoint cache is at that location, near a flat-bladed cactus plant, just up in the bushes behind the cactus. This first waypoint cache (like all other waypoint caches in this trip) is made up of two one-gallon ziploc bags inside each other.
The innermost ziploc bag contains an envelope full of identical clue cards and is marked with the waypoint number. Take one, carefully reseal the rest, replace the waypoint cache, and follow the instructions on the card to find the next waypoint cache. Most of the waypoint caches are marked with bright orange trail tape to help you locate the bags, since they aren't in traditional ammo boxes or anything noticeable like that (although the last cache is an ammo box). I've put rocks on the bags, or stuck them down into bushes in places to make sure they don't blow away. Please be careful to replace them securely. If the number of hint cards is down to less than five, let me know after you complete the trip and I'll go restock the waypoint caches.
Finally, please check http://www.fatcity.com/geocaches immediately before you leave to find this cache, as any important Errata will be listed there. Please take a copy of this cache description, and any Errata, with you.
No hints, no shortcuts and no mercy. :-) Have fun.
