Rode North Star for the first time awhile ago, however last night was my first time seeing it during the night and it looks amazing! However now that north star has nice lights I feel like Valleyfair needs to upgrade the night time sky line. I think lights on the power tower pillars would like awesome, similar to what is on North Star. Wild thing you can't do much more, since its all green, but having some of the taller rides in the park get nicer lighting I feel would make Valleyfair's night time skyline look so much more better!
On a side note here's what I think Valleyfair could possible get in the future, though I don't know what years. Enterprise in wild things helix, slingshot over by where tilt-a-whirl used to be, new inverted coaster that replaces dinos. alive, something similar to raptor at Cedarpoint, a water park expansion replacing Looping Starship, and possible a dark ride replacing the Galaxy Theater.
If the permit for the back of the park is approved that will open up a lot of available land that Valleyfair can use for some rides, including a parking lot replacing Excalibur, possible more water park expansion with this, possible a new roller coaster behind Renegade along with some rides back there a new employee parking lot and a new access road to get there too.
