Appx. W. Mission and Main St.
.5 km from train tracks, north of location, but why now? It's been monitoring since late april, and has just began triggering recently.
As for large trucks, there are extremely heavy and large trucks and loads going down Mission BUT they only go through from 11PM-4AM (middle of the night), whereas these sensor trips have occurred during the day. Also, the g readings are inconsistent with traffic occurring at that time.
