The minimal polygon includes three sides and three angles, so I’ll start there. A single triangle, the least possible entry. And, for that matter, the associated post of our ride to Oro Valley is pretty minimalist too.
And as long as we’re on the subject of smallest allowable whatevers, you may have noticed that the website has been updated to relax the size limit on short comments. It’s now permitted to post a comment with only three characters. OK? OK!
Oh, and by the way: Happy New Year!
