I think tunnels are a must in the near future, as well as, TLC that was mentioned earlier, (though I have to admit, Sunday night was probably the smoothest ride on SOB I've had before. And since it was cool outside I was surprised, because from what I heard wood expands during the heat, and shrinks in cooler weather. I would've thought it would've been a rougher ride.) Correct me if I'm wrong...please!
