Bears- Polar Bear Exhibit. February 17, 2013. While the exhibit does get a large amount of shade in the summer and the pool is nicely sized for Tundra, the exhibit is concrete, outdated, and frankly a bit small. The zoo has both the funds and the space to expand and update it but just no drive. If the plan to get a new Polar Bear after Tundra passes (he is elderly correct?) then they better fix up this exhibit, especially if they want to try to breed the species.
