No sun, no moon.

I am laughing to myself thinking how dumb it was to visit the Observatory with Terry on a cloudy, rainy day.  I had already been there and had seen the hands on displays that let you observe the sun and the moon.  They are actual working exhibits that require the sun and moon to be visible.  I had had the fortune to see them the first time I visited and wasn't too concerned about looking at them again until Terry pointed at that he couldn't see anything on a cloudy day.  Later, he was disappointed that we couldn't go to the telescope to view the moon due to the rain. 

I guess that gives us a reason to visit on a nice day and not worry about parking close.
