I find the sound of a wet chain with viscous goo on it to be very silent and muffled and reassuring until I land with my right leg down in the middle of the lane at red light intersection over the signal sensor and lean the bike slightly to the drive side to increase the profile of metal over the sensor wires. Then looking down, there is a dark round streak on my calf. Oh well. In my younger days, I would clean my chain constantly and lube so the streak was less visibly dark because the oil was so fresh. In my older age, I just track stand or take the crosswalk like a sissy and and don't have the chain ever brush close to my calf. Or I just tolerate the buzz from a dry lube, which still drives me nuts, but my hearing isn't what it used to be, and with a blue tooth device in my left ear, it's less total noise going in.
