none taken millrace. I totally understand what everyone is saying about the look of the rocks and the attempt to blend it in with frontier trail, and obviously the rocks wouldn't be inside the tunnels. No you won't really notice the outside of the tunnels when you are on it, but you will standing in the queue.
Here is what I am thinking. Lets say I build the newest, most futuristic house, it has all the bells and whistles you can imagine, newest gadgets and thingymabobs. I build this new house in Arizona near the Grand Canyon. I decide to paint my house dark blue and have all the overhang supports silver, I don't put a row of brown rock in the middle of it so it will blend in nicely with the canyon.
Doesn't anybody see my point from earlier that MF is going to be basically on the trail anyways. It's not going to be the same serene place it used to be no matter how many rocks you put on the tunnels.
Once again, this is just MY opinion, and I hope I am not giving the impression of being to critical. I know I'll still love the ride its' just that the rocks seem out of place.
