The most adventurous thing I ever did I'm afraid would be X-rated

Not so much adventurous, but cool.
Dived off a maxi yacht in teh Whitsundays because there was ot wind, 150 metrres, say 800 feet deep, 5 miles from closest land and swam around. While out there a whale and calf came through between us and the boat so I was stuck in the water for about 2 hours, they were so close I could watch the calf feed.

My Uncle Sam gave me an all expense paid vacation in sunny Viet Nam. I got to camp out in beautiful settings.

The coolest was touring with Willie Nelson followed by playiing on stage behind Willie, Leon Russell, and Johnny Gimble. The most adventurous would be the almost three decades on the road playing music.

I climbed to the summit of Stromboli (a volcano in the Aoelian Islands) at night and watched it erupt. You see the flash of brilliant red light first, then the boom hits you in the chest. Then the smell of sulfur and the shower of ash. Finally the splat of lava bombs falling all around.

Edit: Fixed the name of the mountain.

Well I trek both East and West of Himalaya and did back to back the Everest Base Camp and Annapurna Base Camp a total of 31 days and I enjoyed it.

I'm not particularly adventurous, but I've earned my open water SCUBA certification and dived a wreck off the coast of San Diego. I also moved to a foreign country I'd never visited, at the age of 39 - lived in Germany for 3 years and traveled quite a bit. That move offered the opportunity to be in Berlin when, then-candidate, Barack Obama, spoke at the Siege Säule, and shake his hand.

I was an adventurous college student who left a group she traveled to Israel with and ventured on her own in Israel with a 40 lb pack and only $100.00 for a month. I can write a book.

I got to the summit of the Mont Blanc many years ago , obviously with a guide . Around the same time tried bungee jumping .
