In my own neighborhood I always stop foot down so I give a nice responsible impression to the folks I live by.
Otherwise, elsewhere I do the foot up stop. Around here almost everybody rolls through stop signs and half of them roll through stop lights too. But there's also quite alot of people who'll wave a bike though regardless of right-o-way which I find pretty generous.

As for the HD riding fashion victims I could care less what they think. The crusty old one lives across the alley from me is a jerk. He walked into my driveway to look at my bike one day, made a noise in his throat and walked away without even acknowledging my presence. He ever does it again I'll tell him he is trespassing. Let him go sit in his garage with his smug attitude debating on whether he wants to risk tarnishing his chrome or breaking down once a month or once every other month. His poor bike sits alot. I imagine he has to save up for towing fees before each excursion just to cover his ass.
Sport Adventure guys wave to me, rice rocket guys wave to me, big touring cruiser dudes wave, dual sport riders wave, people on japanese cruisers wave. the HD riders not so much. Fashion victims are unfriendly I guess.

I was told the law around here is that if you don't put BOTH feet on the ground at a stop sign they can technically give you a ticket...

I am guessing that one of the sales requirements is that no sales to anyone with an IQ over 10.
