I was at AK on one of the coldest January days ever-I think they said it tied some all-time record. Even though several other things were cancelled or delayed, Kilamanjaro Safaris was open and I don't remember seeing any fewer animals than usual. However, FOLK was cancelled (something about the cold and the acrobatics-maybe their contract?) and several of the little animal areas around the park were closed. This was about 5 years ago, so I don't know if KRR was open.
