Very generous friends gave me a Garmin navigator thingie thing for Christmas. I hooked it up used it to find a New Years party that otherwise would have been as remote and obscure as Shangri-La run by Sasquatch monks. Sneed came up and I turned it on for the Clarksville doetag run. On the way back, I hit "home" to get some exact time/distance/shortest route info and it tried taking us out the gate down a closed road. It recalculated when I went left instead of right and got data but when we took the new loop around the North of Clarksville the little car icon just floundered in open space on the display. I guess the Texas downroadload isn't the latest.
It's a great day to have new tech. Gotta love it. I'd hate to be without the internet or digital imaging. Nice to have a map in your head as well.
