Up here in ND evrybody wves to each other, with the rare exception of the Lance wannabees. Even they are reasonalby friendly unless you suggest allowing bents to join in any races. Different story then,
But almost NEVER do you not get a wave from cars, or pickups or other bikers, and only on one occasion have I ever got a middle finger or any crap from a motor vehicle except once at the height of the gas prices from a young long haired tatooed redneck type in a fat tired lifted pickup! Only one time in 4 or 5 years isn't bad at all!
On group rides a couple times a week around here you'll always see a combination of road bikes, a few bents, the odd moutain bike and even the occasional single speed. All in one happy strung out group.
Steel, aluminum, carbon, titnium - all mixed and most people couldn't tell or care about the difference.
But everyone would definitely notice that FLEVO! WOW, I've never seen or heard of one before! I'll have to research it!
