The Marysville station is located behind the fire department building on a patio and is probably the worst site visited so far. In addition to the sensor being surrounded by asphalt and concrete, its also within 10 feet of buildings, and within 8 feet of a large metal cell tower that could be felt reflecting sunlight/heat. And worst of all, air conditioning units on the cell tower electronics buildings vent warm air within 10 feet of the sensor. Oh and lets not forget the portable BBQ the firefighters use a "couple times a week." The area has been constantly added to, what was once a grass rear yard was turned to a parking lot, then more buildings added, then a cell tower with one, then two electronics buildings and the air conditioners...no report on how long the firefighters were BBQ'ing back there, when they figured out why I was asking all the questions they clammed up.
Great pictures, too. Check it out.
