After the reopening of the visitor center I wanted to do a factory tour with my son and nephew. It would be very nice if I could still see Trads in the construction phase. Maybe the chances are not so bad when a farewell model of the Plus 4 is planned.
I'm glad I did a factory tour this year but there were only Plus 4's and Plus 6's in production.
As you say the end of the era of the trads is a good reason to do another factory tour in the Spring when the new visitors centre open. Hopefully there may still be some of the final Plus 4 trads under construction.
