Never flown over any oceans, but I've been all over the US and into Mexico(been down there several times for "missions trips" )
My favorite memory isnt tied to one location. It's actually just the way we did it...
When I was younger our family would take cross country road trips in my dad's work van. He would clean out all the boxes that stored his tools and put in a couple of mattresses and coolers for food. His van had windows on every side and in the back , so as we drove we could watch the scenery go by from the comfort of a large bed basically. Each of us 5 kids would take turns sitting in the front with them, so there were always at least 4 of us chilling on a big cushion. I remember snapshots of these experiences, from when I was young to when I was older. Most of my positive feelings about traveling came from laying down on the mattress and playing cards or reading books. Maybe that's why now I can read in the car without getting sick

I Stood in a Rainbow, August 1976

At age 23 I was backpacking on Mt. Shuksan near Mt. Baker. We camped above the tree line at around 8,000' elevation. That evening we saw the sunset behind Vancouver Island, British Columbia.

The next day a massive storm blew in. Hail piled up like snowdrifts, washing ptarmigan birds downhill. ("PEEP! Peep... peep... pe...." ) Lightning struck around us. ("Here, you hold my ice axe." ) Pouring rain soaked us to the skin. The sun shone in a nearby valley.

And we stood in a rainbow. We could see the rainbow colors on each other's faces. I stuck out my arms and marveled at the colors on my arms. It only lasted a minute or two. We were not high. My hiking partner was a medical doctor.

Afterwards the sun steamed our backs as we slogged our way to the car.

This was a peak experience of my life.

Twice being in trouble with the police...in Italy in 1988 when our 18 year old nanny was homesick and phoned home alleging that we were keeping her in Italy against her will. Her father went to the police at home in Belfast and they contacted the police in Italy and they sent the Anti-kidnap Squad to investigate....at that time there had been a spate of kidnapping in Italy by the Red Brigade! Not amusing when they arrived wearing jeans, T-shirts and sub-machineguns! The second time was in Germany in around 1998 when my husband and I were stopped and arrested for smuggling and money laundering...held overnight, our stock of valuable stamps and philatelic items, and all our money confiscated, we were carrying quite a large sum in various currencies as this was before the Euro, and we were doing business in ten different countries and currencies. Both times we were completely innocent of any crimes or irregularities, the first time in Italy the nanny admitted to the police that she was there as our employee, and was being paid to look after the children...incredibly one of the Italian police officers actually asked her out on a date! The second time was much scarier and we had to hire a German lawyer, who by sheer good luck, not only spoke fluent English, but was also a Stamp Collector! He got us released and allowed to return home, but without our money or our stock. My husband returned a month later to a court hearing where a judge dismissed the case and he got everything back plus one month’s interest on the money, which our lawyer insisted on. We then paid the lawyer his fees in the rare stamps he needed for his collection...!
