To be clear this is not a motorcycle trip! I'm trying to make the most out of about 5 days at Yellowstone with my girlfriend. We're in the very beginning stages of planning it out, and we don't have a date planned yet so any recommendations for a great time to go would be appreciated. We figure we'll fly in, rent a car and try and get different AirBNB's out there as I'm sure there's some cool places to stay. Any advice to get the best out of this trip would be appreciated. Also if there's any type of motorcycle rental that would be amazing.
