I am soooo envious of you Torontonians with your great zoo! And now you've got stingrays... too cool!
Seriously, if you get to feed them, go for it! They come up and rustle over your hand, and grab the little fishy. You can pet them with the other hand... think wet velvety leather. After all, how often does a lady get her hand kissed these days????
We'll get to see the Calgary Zoo for the first time this summer. Maybe next year to Toronto, and the zoo will certainly be on my list of must-dos.
