A Hovercraft from Portsmouth to the Isle of Wight.
A Twin Otter aircraft from Mwanza to Bukoba (and back) in Tanzania.
A small helicopter (I was very young and hardly remember it).
The People Mover at Disneyland!
A single engine Cessna.
A Anchorage-to-Denali luxury train.
A whale-spotting cruise.
A llama.
A donkey during a basketball game.
A hot air balloon. Everyone should do that once!
A freight train locomotive.
A boxcar.
An ambulance. As a driver, and as an EMT, and as a patient. Not all at the same time, but the same ambulance over a period of time. Everyone should NOT do that.
A 100’ aerial ladder truck.
Oh, almost forgot:
The back of a moving van.
For what provided the greatest thrill? I’d say the cruise we went on a few years ago. I stepped aboard the ship and marvelled at its size and general aspect in view of the fact that it was still a self powered oceangoing vessel. Besides, cruises are so evocative of the bygone days of ocean liner travel. I am too young to have experienced that so this is a nice runner up.
Flying, generally, still gives me a little zing of excitement, but it’s way less than when I was 6 years old and got a helicopter ride. I would like to fly somewhere in a DC-6, Lockheed Electra, or other vintage, turboprop-driven transport plane. I think flying lower and slower would bring back some of the thrill of my first time in a plane. But I can’t think of where I would find such a flight. They’re certainly not flying in or out of LAX.
Private jet, the “Wachovia Shuttle.” I don’t remember what size exactly; I guess I’d say it held about 8-10 passengers. Very cushy. Flew it from Winston-Salem to Atlanta and back.
A “cyclo” - Vietnamese three wheeled pedal powered rickshaw thingy in Saigon.
A hydrofoil
A tram (or streetcar) - shaddup Melburnians, it’s exotic to me! 
A monorail
A miniature steam train
A full sized steam train
A funicular railway or two (both touristy, and the Hong Kong one is pretty mainstream, but the one near Sydney is the steepest railway in the world)
A driverless train
The driver’s compartment of a commuter train
An articulated bus (bendibus)
A double decker bus (not common here)
A Sydney train that arrived on time…
Oh UncleBill, how I hate you. My jealousy knows no bounds. 
Does an M113APC with a TOW count?
Tripler
Someone already said a Huey helicopter.
Hmmm…, lots of fellow Bullet Train and helicopter riders here.
The chair bridge that used to be under the San Bernard River bridge over I-10.
We had a rope we used to swing across Buffalo Bayou when I was a kid.
Probably too many have hopped a freight for it to count.
Way popular; I’d have to think for a bit to figure out how many times I’ve done that.
140 mph in the trunk of a car?
A few Super Connies.
Several small airplanes.
Do parachutes count? They were all the old military model called, IIRC, the B-10.
In the trailer of a deadheading 18-wheeler.
Wow! That countach looks like it’s doing 200 mph just sitting there!
Piggy-back. Sure.

A WW2ish german bakers bike.
Roller blades
The Tube ( London)
Subway ( NY)
EL In Chicago
Stolen Golf cart at midnight
A Donkey in Ireland.
**Hedra’s ** tortoise ride just takes the cake, IMHO.

Whilst apologizing for pounding the enter key in frustration, I’d like to add, belatedly, I’ve survived Mexican taxi drivers, numerous hydroplane crossing to Mackinac Island, Car ferry crossings, and German rail in the heat of the summer ( no air or deoderant)
I thank you.
Ohhhh, and I once fulfilled two Life Goals ™ at once by a) driving our tractor on a main road, and b) fricking up traffic for miles because no one could pass me. 
That was fun.
There was a demonstration track at the World’s Fair in Vancouver in '86. Quiet, and smooth with a capital “smoo”.
yak in Tibet (horses there too). Did the old cross a river while sitting on an inverted T bar as the pully slid down the cable trick a couple of times in Tibet as well. Some pretty odd tractor like contraptions in China. Really old propeller planes of Russian origen.
A little boat drawn by two dolphins in gear.
Really!
I was 6 years old, visiting the Dolfinarium (Dolphin-show) at Harderwijk, Netherlands. I was picked out of the audience for the ride across the large pool because it was my birthday. Or maybe it wasn’t my birthday, but I had an ambitious and determined mother.
Riding the ski-lift in Switzerland in summer was nice too. It is like flying across this beautiful view at a height of 4 metres, in total silence with almost no people around.

What is that? It sounds interesting!
I would like to point out my (just noticed this second) error. A kamik is a boot, whilst a komatik is a sled. Sorry.
Also, I see tractor on the list somewhere in here - I learned how to drive on a tractor at the age of 11 or 12, so it didn’t strike me as exotic.
Oh yeah, riding on a huge farm combine is pretty cool. I mean, it’s commonplace for some people, but I didn’t grow up on a farm. When my uncle farmed, I loved going in that huge rig with him. His toddler daughter would go with and fall asleep on the floor of the cab. Which is incredible, because those things really vibrate.
When I first opened this thread I thought, nah, I’ve never done anything exotic. Reading through jogged my memory…

– The cable car over the East River in Manhattan
– Monorail

Wow. I have done a thing or two!
