No, most of the time we don't....
We need frequent breaks anyhow to stretch our legs, go to the restroom, etc...
We always have bottled spring water, fruit juice jammers, etc... with us. And, snack-bars, etc...
But, nope, the only time we go thru the trouble of packing a meal is if part of the destination/journey might be some kind of picnic.
There is enough work to deal with packing, etc..... to get ready for a trip, that the last thing I want to do is add to that.
Usually one can find healthier choices other than McDonalds type fast food if you want. My husband really watches what he eats, and even if fast food is the only option he can usually find a grilled chicken sandwich, salad or wrap or something. He will often have protein bars and a piece of fruit handy as well.
But, nope, no tailgating for us.
