I second that, as I don't think I've seen any episodes from the second season, sans anything released public domain or the old Columbia House videotapes from 10 years ago.
Not an official announcement, but the CBS Distribution Bible is reporting that they have finished transferring Season Two of PETTICOAT JUNCTION to HD. That probably bodes well for a dvd release in the near future!
