I was back at the zoo on Sunday (sunny but cold) for the first time in a while and three comments on developments:
1) Boardwalk - the Americas/Africa boardwalk was closed again for "construction". I don't know what they were doing to it - but maybe it wasn't quite ready after all for March break?
2) Winter Zoomobile - I really try to not criticize the Zoo, but this was my first trip on the Winter Zoomobile and I wasn't impressed. It could be that it's currently being used to shuttle people back and forth with the boardwalk being closed - but the route stayed on the pedestrian paths (other than the back of the admin building), the only animals it passed were the Himalayan Tahr, and the pre-recorded messages weren't that informative or value-add. I suspect it's very helpful to people who may struggle to get around, but I won't use it again unless the route changes again.
3) Polar bears - I had read (somewhere) they wanted to convert the pool to salt water, but can't recall reading about them adding a chiller to the pool for year-round use. The volunteer at the polar bears wasn't sure when it was happening (had thought it was going to be spring - but said it was more likely in the slower months next fall/winter).
Other items of note (but not worth starting an entry in the discussion board):
1) Stellar Sea Eagles are back in their exhibit - so presumably no successful breeding, and
2) Tundra - polar bears and wolves were very active first thing in the morning in the cold but sunny weather.
There was good "engagement" with volunteers throughout the day which was nice to see.
