Ya, I'm a waver, I wave and say good morning/afternoon to everyone, bicycle riders, dog walkers, jogger, roller bladers, etc. Still I never expect anyone to wave back but a lot do. I rode motorcycles for 30 years, each, type of scoot rider has a special wave so I guess I need to learn the "specific wave per type of bicycle.
I took the decals off my POS Roadmaster MTB-clone and i've noticed that when I'm riding local area "EASY" singletrack, the REAL MTB riders will do the "head nod", then give me a really disgusting look when they see the austabula crank and realize I'm on a Wally-Mart Special

When I rode MTB's back in the early 80's, no one CARED about what equiptment you had or weither you had a "specific style" of bike for the type of riding, now it seems the "1st. thing that happens when you slow down and meet another MTB'er, is they do a automatic scan of what you ride and it's level of equiptment to see if you worthy of their company, SAD.
Oh well, I just wave anyway, continue my ENJOYING MY RIDE and hope they are having as much FUN as I am.

I guess I'm a FRED too as my jersey is plain and I wear black bicycle shorts cause there CHEAP next to the way cool baggy MTB shorts, well that and I'm old and fat too, LOL!
