Range of food

I find it hardest eating out and about.  The fact that life everyday means planning what and how I eat.  A simple day trip is taking food with me.  A trip on the train, coach, plane means either taking my own food or settling for junk.  The hardest thing is the lack of understanding of others.  I'd love to find a way of changing peoples understanding and out look.  Things can be so much better.  Thats the bright part of this thought process.  Thats the way to make the changes. :-)
