Mark responded to my City Observing Session report:

It was a very rewarding night for me at High Park. Not only did I get to see Uranus for the first time (I can check it off my to do list), but with help from Blake and his information gadgets, I was able to clearly see the Great Red Spot on Jupiter. At first it was subtle, but as jupiter rose in the sky and as the seeing improved, there were moments of very nice views of the GRS.
