I stop.

And remember, all 50 states consider bikes to be vehicles. So it is possible for you to get a ticket for rolling through a stop sign.

I remember an acquaintance telling me about using his driver's license as id and getting a ticket for some behavior while cycling - and he apparently had quite a battle with his auto insurance company not to have that counted as a negative on his insurance rates. (OK, this was a long time ago, but still!)
