I got to ride in one whose owner sold rides at an air show 40 some years ago. Very noisy!
I got to ride in one when I was about 12 years old - my father took me to an airshow and he got me a ticket for a ride. The plane basically made a big circle around the airfield and landed. I remember the noie and the vibration! Well, many years later, just last year, I was at an airshow and got to ride in a Tri-Motor for a second time! That was fun!
