More About Shortcuts In Utah
There are actually three shortcuts in Utah. Only use the first two (these shortcuts are on the right.) When you get to the third shortcut, the shortcut is on the left. Go to the right. The reason is because there are plants that you must dodge in the third shortcut. It's easier just to not to take that shortcut. The shortcuts are also useful in Time Travel. (It will take less time!) And of course you can get ahead of your opponent in 2-Player Mode.
