I lived in Talise before. There were like 10 days in a year that I smelled something in the air, especially around 7pm - early morning. The worst smell would actually be around the entrance to Lambert Ranch though. After I moved to Sierra, one day I smelled it & file a complaint, and the inspector called me right away. The crazy thing is I was the only one to complain on that day. Maybe ask your friends to drive on Tomato Spring around that time in a month to see if they smell anything?
