Does anyone know anything about GPS vehicle tracking systems. I ran across a site, www.advantrack.com, that has tracking systems for vehicles. I thought that it could be helpful with watching over lawn care crews. Some of the systems let you see exactly what roads the vehicle was one and at what time. They track speed also, so one would be able to know if the driver was speeding. The system seems like it could be very useful for someone who is running multiple crews. Just thought I'd let ya'll know about it, and see if anyone has used anything like it before.
