The cache IS at the posted coordinates, but you'll have to complete the challenge in order to log a find.
I wanted to do something a little different for a challenge cache. I have to admit, I stole this challenge idea. I've seen it in a couple different places and I just thought it was a funny little challenge idea. Looking through the attributes this site allows us for our cache pages, I've always though the "Look out for cattle" attribute was a little silly. I can see where it might be needed in some free-ranging places out west, but it has to be a rarity where this thing is used legitimately. More often I think it is used simply because it is a silly attribute. I think I even saw it on an event page once...In any case, this challenge is simple:
Find 50 caches with the "Look out for cattle" attribute!

That's it, pretty simple. Somehow I have found 106 with this attribute, so I know it is doable. Those that have been "out west" in free-range areas will have an obvious advantage. I did a pocket query that came up with over 300 within 100 miles from home, so it shouldn't be too hard. You can display you meet the requirements any way that you wish. You CAN use this cache as one of your qualifiers if you are short one.
For the actual cache itself, this is a location that I have long considered for a quick roadside cache, but this fits the challenge perfectly as there are always cattle grazing near here. In fact, several watched me hide the cache. I swore them all to secrecy, so they will not help you! You are looking for a peanut butter jar hidden in pretty typical fashion. About the only other thing I can say is that this area floods after heavy rain, if you don't think you can drive through, you probably shouldn't. Also, feel free to "pre-sign" if you don't qualify. Then you can just log it when you do. Cache on!
