"...having seen several rhinos in the wild..."
Not that "huge" from the distance we were at.First time was about 35 years ago in Ngorongoro Crater in Tanzania.We were a couple of hundred yards from him (her) but the guides refused to get any closer out of fear.
Of course that same day they got us within about 20 feet of a small pride of lions just hanging out,resting."It's OK",they said,"they've just eaten".Kid you not!
