Has any been found yet in Maine? ...or are they still in the distribution stage....
Does anyone know?

They've apparently been released in some areas - a few started showing up yesterday. Here's a link to the Jeep site, and there's a link that shows where Jeep TB's have been found so far.

Since BRDAD was the central Maine distributor for the last event, perhaps he can tell us? :D
