Verizon's offers free traffic alerts via text message
We're doing everything we can to NOT spend any of the upcoming Fourth of July weekend in a car (we'll probably spend it either illegally modding fireworks, or far more likely, blogging about illegally modding fireworks) but if you are planning to take to the road, Verizon Wireless is offering a free service (or at least it's free for the holiday weekend) where you can automatically get traffic updates delivered to your phone via text messaging.
