Expanding or contracting circles?

So, if the circle contracts, it condenses into a point.  If it expands, does it expand into a point as well?
Last night, we were finishing up supper as we realized we had just missed taking a great picture of the full moon rising over the hills above the ranch.  This morning, Betsy checked her Facebook.  I can't tell you how all this works, but you know:  she found a picture, "liked" by someone she knew, that was in fact, a picture of the moon rising over the hills in the Paradise Valley here in Montana.  And the person who had noted it, and liked it was a person who lived next door to one of the Archibald cottages at Lake Rescue in Ludlow Vt. 50 years ago!! Get the point?!

Two nights ago was our first night on our own- Matt the manager of the ranch was away and we did our midnight check driving the Gator up through drifting snow to check for newborn calves. We made it through the whole herd, successfully found the three calves already born, witnessed no newborns, and breathed a sigh of relief.
Yesterday we had a great cross country ski up at the top of the valley- no souls in sight, but beautiful conditions.  We had Ginny over for a Sunday roast chicken dinner- and learned amazing stories of the town Aldrich, next valley over, that is now a ghost town, and on the property of the cult, Church Universal and Triumphant, but back in the day, residents from Aldrich and the Tom Miner basin would get together for barn dances once or twice a year.
We heard bad news from the Doolittles- they will have to put down one of their horses, one we have cared for in years past, due to a severe leg injury. We will try to catch up with them a little later in the week for a drive through Yellowstone up to the very isolated Cooke City for a diner lunch and some wildlife viewing.
Ginny runs books and copies of the Christian Science Monitor up for us to read- I feel like a 9th grader who can't quite get all his homework done!  Just finished Annie Dillard's "An American Childhood"- fabulous writing!
Had a chat with Matt over coffee this morning- and discovered that what we have been reporting as seeing as "snowshoe hares"- the size of a deer and all white- are actually an expanding population of jackrabbits that had been low in numbers in recent years but appear to be (sorry) rebounding.
