Sorry for the slow reply. I've been on travel in Germany and Austria. The trucks over here
really are very cool.
Another good question. Left to myself, I would have recombined them years ago. But again, I am sceptical that we can encourage increased activity in those subjects by recombining them. (Perhaps I'm cynical, but I seem to think that it is much easier to discourage a type of building here than to encourage one.) Again, I am absolutely open to it, and if there is interest and call for it than we will see what we can do.
