Some friends and I will be in Great Falls next week and were thinking about a day trip to Yellowstone to see the old faithful geyser.
According to Google maps it's a 5 hour drive each way (I15 south to MT 69, to MT 359 to US 287, etc). Just wanted to ask some locals if it actually takes this long? I've found Google can sometimes be off when it comes to secondary highways in their time estimates.
So basically how long is the drive, and which route do you recommend?
