In south county too...
With Sensorly, I was loosing signal completely at times, near Ave B & Cty 19th. In San Luis AZ the same, when you move away from the Hwy 95 corridor.
On a side note: It's fun mapping with Sensorly..... I find myself looking for places to drive though on my trips just so I can map it.......
(Can't wait for LTE......)
