As the rating shows, this is a challenging geocache to claim due to the inherent risk associated with the terrain. Make certain to bring a pen, as there is nair one to be found on-site. Remember, the physical log MUST be signed in order to log this as "found."
The following description was paraphrased using the geocache description of the original geocache that resided very close to this location: Ent Bait (GC5J17Q). Same rating, same attributes, and of course, same foolishness. The host at the originial location (N37° 16.103 W76° 45.755 if you'd like to swing by and pay a visit) has started to show some aging and should likely be retired from service. However, a "nextdoor neighbor" has stepped up to offer continued geocaching fun and shenanigans in a similar fashion.
Have you had enough of all the typical park-and-grabs? Are you craving a cache that will get your blood pumping? Do you walk the Earth with a mild level of insanity in your genes? Well, if you answered yes to any or all of these questions, this cache is probably for you. High-adventure geocaches, with difficult terrain, can be few and far between. This cache helps remedy that problem. A simple tradtional style hide, but with one major difference: when you arrive at the posted coordinates you will still be approximately 25-30 feet away from the cache.
You are looking for a camouflaged bison. Once you get close, it will should present itself.
This cache is not for the faint of heart or those with a fear of heights. Pursue this cache at your own risk. If you are looking for an even more intense adrenaline rush, try to find it at night. Note: The "stealth required" attribute was included, as it was part of the original Ent Bait attributes. However, I'll be the first to admit ... there is only so much "stealth" you can impliment when doing what has to be done. 
Happy hunting, have fun, and be safe!
Congratulations to the team of terri and billy, renruts, and the dibcrew on bagging the Williamsburg vacation FTF!
