Something else I learned is to NOT leave your GPS logger sitting on the hood of the vehicle you're driving. I had set it on the hood so that it would get satellite lock before we left the house and I forgot to put it in the truck when we left. When I remembered it we drove home and looked for it. Sadly it's gone so I'll have to order another one. If you're curious the GPS data logger I use is this one: AGL3080: Amod AGL3080 GPS Data Logger.
