Going off what @BoddaH1994 said, Adventure Express's minimum operating temp is 45 degrees, and as soon as the thermometer goes below 50, it runs really slow.
With Racer, however, its minimum operating temp is 35 degrees. The other morning I was helping opening up Racer and it was about 38 degrees when we did our morning checks and Racer was running pretty good considering the cold temps. Having The Racer open for Winterfest is a great addition to the lineup.
Also idk if this is being discussed yet, but Fastlane for Winterfest? When I look online at Fastlane, says it will be on sale soon. Considering that two coasters are now joining the Winterfest lineup, could we see Fastlane implemented for Winterfest and the end of the single rider lines?
