Nothing negative has been said. It's just the constant attention that is sometimes annoying, I must say!
One time a guy on a motorcycle followed me around a parking lot and pulled up alongside me. He was grinning and said, "What the he** is that thing?! That is SO cool!" I told him and he pulled ahead of me, shouting, "Think I'll look into getting one of those things myself!". Then he took off down the road.
Interestingly, more kids make comments and more adults avert their eyes, acting like they don't see me (at park and bike path). Guess kids are more "open-minded".
That's one reason I love 'bents-most bent riders are very open-minded, off-the-wall, and "child-like", meaning open to new experiences and more playful in their nature.
