I am was heading to Nashua Airport and i guess they don't see snow that much because i saw all kinds of trucks in ditches and spinning out on the highway. I took my TomTom that is old and it came up and said "alternative route 15 minutes faster", I chose that because people were driving like Miss Daisy at 40MPH in the left lane.
It also told me that traffic was adding 50 minutes to my route. Anyway, I got to the airport on time and went around all the traffic so i would buy a model with the free traffic updates. I am on my 3rd TomTom only because i like to update my electronics, though will be awhile since mine has free map updates too. So i would pay the extra and get the traffic option unless the new ones have it built in but i didn't see that.
