Years ago Fred Rau of MCN wrote a column sharing his observations from visiting 3 major rallies in one year. To the best of memory here were some of this comments.
Americade
Lots of Goldwings.
Lots of folks riding with 3/4 helmets and matching satin jackets
Riders up early, moderate length rides, about split between it being a riding event and a social event.
To bed early.
Nearly everybody stayed in hotels and motels.
Sturgis
Lots of Harleys, duh
Lots of no or half helmets, and heavy boots. Joked they seem to be much more concerned about foot injuries over head injuries
Riders up later, to bed late with lots of time socializing, shorter rides, more of a social event then a riding event.
Mostly people staying in motels, hotels with some camping.
BMW MOA
Lots of guess, BMWs
Lots of full face and modular helmets as well as hi-viz textile suits. (said they look like human highlighters)
Riders up early, on the road early, late nights in the beer garden.
Long daily rides. More of a riding event then a social event.
90% camping
I will add my GWRRA rally observations
Same as Americade except Lots of trikes, walkers and oxygen tanks. (Not a slam, fact is our GL demographic is aging)
People get pissed with you laugh out loud during the light parade.
The thing I liked about attending MOAs is they are in a different location every year. Been to Sturgis, once was enough. Been to Americade so long ago. Would love to go back.
Motorcycling is like ice cream. There are many flavors for a reason. We all like something different. And... all ice cream is good.
