I agree. There's not much more you can do to Montezooma to improve it. It's a great ride as is. If I had to scrutinize for improvements, you could repaint it back to its old school colors, give it a cool new lighting package, and maybe restore the sign.
I also agree on your suggestions. That area is good on flats, but a couple more wouldn't hurt. Like I suggested earlier, a small one on Jaguar's final helix, and Windseeker's old spot.
Ditto. The area needs a lot more shade. Give that area some legit Mexican food as well. The place by Revolution is always shut down, even on the busiest of days.
I feel like Knott's used this year as a break from new rides. Sure they retraced Ghost Rider, but I think they used it as an opportunity to save up for next year. Hopefully they'll invest in both a new coaster and a new area, but we'll find out for sure in November.
