Seeing the changing of the colors of the leaves is something many people want to see. I have been able to see the beginning of the change but not the vibrant colors you see in pictures. We have been to a few of the places on the list and they are truly beautiful. The Columbia River Gorge in Oregon is wonderful especially the Multnomah Falls. Zion National Park in Utah is a stunning park with canyon trails, and mountains to view. Vermont and Kentucky are also very nice places. It is a good list for sure. https://www.lonelyplanet.com/usa/travel-tips-and-articles/the-best-places-to-see-fall-colors-in-the-us/40625c8c-8a11-5710-a052-1479d2754ad1

When you make it to a large major airport it can be very difficult to get to you flight, extremely crowded and can be prone to delays due to how busy the airport is. When we can we try to find less busy regional airports that are usually cheaper to fly into. Here is a pretty good list of smaller airports near large cities that can be better. https://www.tripsavvy.com/the-best-alternate-airports-for-major-regions-4155909

A new list ranking the best food experiences has come out. Donna and I have tried a few like Pastéis de nata in Lisbon, Portugal, Pizza in Naples, Italy (its not the same Pizza you are used to here) and of course Beef Brisket here in Texas. Check it out! https://www.cnn.com/travel/article/lonely-planet-500-ultimate-eats/index.html  

This looks like a really interesting way to tour India and see some of the many historic sites in India. India is definitely on our list of unique places to visit in the world! https://www.cnn.com/travel/article/maharajas-express-rajasthan-india/

If you want to make the most of your trip and have a long layover you have options of going out into the city and taking a tour. Donna and I took an extra tour of Lisbon, Portugal when we had a 15 hour layover on the way to Barcelona, Spain. It was a great tour, we learned and saw a lot and beat some of the time at the airport. While you can make your own tour like we did you also have other options that include local guides provided by airlines. Here is an article going over some of those options: https://www.cntraveler.com/gallery/how-to-make-the-most-of-your-layover?mbid=social_facebook_aud_dev
