GQ has a YouTube series where they interview celebrities and sports figures asking what there 10 essential are. Let me take a stab at my 10 travel essentials. 1: My Nikon D5500 with an 18-200mm lens. This is my daily carry camera, and I almost never leave home without it.
2: My Chromebook, the current one is an Acer, it is the third one I have owned. It is a 12 inch, weighs less then 3 pounds, and is easy to travel with.
3: Airline travel credit card. I have more than one. The air miles from them have paid for a lot of travel. Over the past 4 years, I have all but stopped using cash.
4: Cash, I always have a modest amount of cash with me. It is rare that cards won't work, old habits die hard I always have real money with me. I keep a enough Euros and GBP on hand to take a taxi to a hotel and have lunch when I arrive.
5: Passport card. If I am leaving the country I carry my passport, but I always have a passport card with me. It works for border crossings in north America, and at the airport.
6: The flying pharmacy. I take just a couple of prescription medications, and I always have a few days supply with me, along with anti inflammatories, digestive aids, and antihistamines. There is also a hair brush, toothbrush and toothpaste in the kit.
7: Mobile phone. I am carrying a Samsung, 5G phone. I seldom talk on the phone. It connects me to email, and I can post to my blogs from it, do web searches, and get directions.
8: Electronic support bag. I keep this packed and ready to go, it has chargers for my phone, Kindle, and Chromebook (and Apple lightening.) Also other cables, and a PowerPoint remote control, I like to pace when I am speaking.
9: Asics Cumulus Gel shoes. I have multiple pairs of these, and they are the shoes I wear 95% of the time that I have shoes on. I have them in plain black for semi-formal occasions, and neon yellow when that is what I feel like. I buy them when I find them on clearance, or when I see a color I love.
10: Travel Penguin. He seldom appears in public, but he is in my essential travel bag. Oh, the adventures he has been on, the things he has seen.
