we walked the entire zoo in 3 hours...this included all exhibits, a train ride and lunch...
lunch was ok. it took 15 minutes for my son's corn dog to cook...annoying!
many exhibits were closed and under construction.
I felt soooo bad for the elephants. they were in a small enclosure and could barely turn around with the 2 of them in there. no one was even there working on the new exhibit...made me angry to see. farm area was closed. other animal exhibits had just 1-2 animals and you could never find them in the exhibit. we did see and LOVE one red panda.
this zoo doesn't compare with brookfield and san diego zoos...but we did like all of the gardens throughout the zoo.
