If you really wanted to take a scenic road trip from Columbus, Ohio directly to Yellowstone National Park, it would take about 26 hours if you drove nonstop. It is a whopping 82,190 miles, and it would cost about $12328.5 in gas prices, considering the average amount is 15 cents per mile. It is much cheaper to fly and have it take 6 hours rather than a 26 hour costly trip.
FUN FACT: Devastating fires have swept through Yellowstone due to recent droughts, killing much of the trees. A lot of the trees were already dead, due to an outbreak of beetles that eat the trees. This is why the fire spreads, because the dry, dead trees can easily catch fire and fall over and spread it to new, living trees.
