Yellowstone - buffalo

The first seeing of the magnificent buffalo (Bizon bizon) could not excite me much - 2 rangers hold my DL hostage and I have to comply with the 'Follow me. We need to finish our talk.' instruction. (I was stuck in the snow trying to get to teh Old Faithful from the northern entrance..) The rangers could have been better Santas on the very Christmas day than giving me a ticket for driving on a closed road.
Nonetheless, there is much more bizon (and any kind of wildlife) to enjoy roaming in the fields, on the roads. The real close encounter of 2 buffaloes, oblivious to the outside world for being entirely in their own universe (but not entirely so that they kept walking on the shoulders of the roads, following some newly acquired evolutionary advance to stay on the road itself as little as possible and only when needed to cross it) walking along the road in the night is one of the greatest treats, and thrill, of the whole excursion.
