My brother and I went to the zoo here in Detroit a few weeks ago. Its not the best zoo ever, but it did have:
-Some chimps doing very dirty things to one another.
-A black bear I really wanted to hug
-2 very active Rhinos
-Wandering peacocks
-PENGUINS!
The pics I took that didn't suck are found here (and most of them still kinda suck).
