Take one bison tube / pill container, layer a couple of 4x4 posts and wood planks side by side, sandwich them together with some lag bolts, cinch them down tight, paint it brown, and voila!! A bison tube sandwich!
The cache is a small pill container / bison tube, log only. Bring your own writing stick. There's parking just a few feet away, just be sure that you're fully off the road. Try to look at least a bit normal / stealthy, as there is on occasion local / tourist traffic along this road. Pretend like you're taking a picture of the sandwich or something.
As always, be safe and have fun
