Now that sounds like a plan! Y'know, when I heard that they wanted the 30/74 the first thing that popped into my mind (even before all the four letter expletives!) was "Will it even fit on those tight curves?" and if someone like me would think of that you would hope that people charged with the administration of "historic preservation" would think of it as well! (Uh huh! Riiight! Suuure they would!)
This has all the earmarks of a clandestine plan that blew up in their faces and now they are scrambling trying to solve this problem on the fly (essentially making it up as they go along). It would be amusing (and I would get a bag of popcorn and a soda and sit back to enjoy the show) to watch and see when their house of cards that they keep trying to shore up comes tumbling down around them but, sadly, it's only depressing and demoralizing when you realize that it's a priceless treasure that they are in the process of destroying!
