?OTD

One correct response on yesterday's question--nice work, Ron.
There are an infinite number of places on Earth where you can walk one mile south, then one mile east, then one mile north and end up where you started. They are:
1) The North Pole
2) Any point one mile north of the place where the circumference of the globe is one mile.
3) Any point one mile north of the place where the circumference of the globe is 1/x mile. (in this case you'll have to make more than one full trip around the circumference before heading north)
Today is a day off. Hopefully I'll have another good one for you tomorrow.
