Screw Up, Nit Pickers, Rivet Counters?  Is this why models cost too much?

I have seen this in other hobbys too.  
Me being a professional museum model builder for military vehicles and aircraft.
ABC Model Co. would change models every know and then in a real cheap way. Just changing or drop 
more decals into the a box.  Now that F-104 can be made into a German or Canadian F-104.  
But as soon as that happens rivet counters flip out. The German F-104 had this the Canada F-104 
looked like that etc. etc.  it is the same model just with new decals.  Should people be happy

One of the nice things about our hobby is that if you get tired of working on one area you can do something else. Such is the case this very hot Florida weekend when I decided to lay down a couple of streets. Using some tips from a past post I found here on MRH on building concrete roads, my first step was to spray on a coat of flat aircraft grey, which as it turns out is almost a concrete color. Then when that had dried I used Woodland Scenics concrete top coat over it and let that dry. Then with a fine tip marker added the tar crack patches. Good so far.
