Highly speculative, I know, but it was either this or musings on what the new “Alf” remake portends for civilization. I figured there’s more reader interest right now in the veepstakes than there is in “Alf.” Slightly more.

Is tomorrow the day?

Take note, veep watchers: Earlier today, a charter plane took off in Boston, stopped in Chicago, then flew to the tiny airport in Janesville, Wis. Janesville, of course, is the hometown of Representative Paul Ryan, a top vice-presidential contender. According to a source on the ground, the plane is still in Wisconsin.

Tomorrow morning, Mitt Romney will visit the USS Wisconsin in Norfolk, Va. For what it’s worth, Ryan is scheduled to be on vacation in Colorado.

That’s Robert Costa, noting that one of Romney’s sons was also in Wisconsin today. My gut tells me that Mitt won’t roll out his VP on a weekend, since it means less media coverage and more distractions for voters. But I would have said the same thing four years ago and that didn’t stop Obama from formally introducing Biden on a Saturday. Another interesting detail: If you look at where the plane in question — number N26SC — has been lately, you’ll see a lot of destinations that would presumably be relevant to Romney advisors and staff. Ohio, Janesville, and Teterboro, New Jersey on Thursday, the same day that Romney was in the state for fundraisers.

One teensy problem, though. Unless I’m misreading this, the plane is based in Monroe, Wisconsin. Seems unlikely to me that that would be the case if it’s a charter that a Boston-based campaign has been using regularly. More likely, it’s a plane owned by some local Wisconsin corporation that the company uses for business and the Ohio/Jersey destinations lately are a pure coincidence. Ah well. Even so, if you want to play around with tracking flights based on VP speculation, the FlightAware website is fun. Keep an eye out for that mystery charter from Boston to Trenton…

Exit question: Who’s up for some Alf?
