I'm with Theodore on this one. I take my phone but I don't look at it until break. Not so much while driving though. @Theodore_Kent is hardcore. I heard he can shit, drive, chew gum, smoke, do crosswords, drink, and check his phone all at the same time... I have to have mine with me. I run a business so its not really an option to leave it at home. When we go camping we all (my family) power them off and leave them in the vehicle. Its probably the only time I see my old lady go more than an hour without looking at her phone.
