If we are stopped at a traffic light and someone sticks their head out the window to ask, we say TOO MUCH! If we are parked somewhere we usually give them a close idea. We were in, can't remember the name of the town, on a Navajo Reservation, north of Holbrook, AZ. We had stopped to eat lunch at a Hardees'. This family was walking in as we were getting our gear off to go inside. They had a teenager with them that appeared to be physically challenged. He looked at me with the biggest broadest grin on his face and gave me three or four thumbs up. I think that was one of my best memories of anyone admiring my trike. We get asked that question alot. I really don't consider it rude, but every person has their own opinion on that.
