Live is an adventure, but it has been said that an adventure is a poorly planned expedition. Most of my expeditions are pretty poorly planned .
But some of the top ones were:
Getting drafted into the army. 3 years but I mostly survived.
Motorcycle trip around Europe, North Africa, and Scandinavia. 6 months. Camping trip, rain snow, equipment failure. A true adventure.
Hiking the kings trail in Sweden . A month overland from 150 miles above the arctic circle to just below the arctic circle in fall. Good planning and you can do it in a week, two at the outside.
Motorbike trip from SLC to MY with a 3 week side trip to Germany and back. This was probably the best planned expedition that I did. Almost nothing went wrong. Also my last great motorbike trip.
Car trip from SLC to Inuvik NWT Canada. 9 weeks. Similar to the motorbike trip around Europe, but with more rain and less time.
Trekking to base camp in nepal. 4 weeks. It takes 3 weeks of up hill hiking, camping in the cold and rain, eating whatever. I tried not to ask, although the Yak was pretty good. Only a week to get out. Several weeks back home to get health again.
A couple of years ago I did a month road trip around Iceland but it was really planned by someone else.
