Are there any ranches or land for sale that borders and joins yellow stone national park?

My parents currently have a property for sale 20 about 20 minutes from the West Yellowstone entrance into the park (in Island Park, Idaho). I don't know if its at all what you're interested in but if you are you can email me through my profile and I will give you contact information. It's on .24 acres, 2 bedroom, 1 bath.
