Portable Art: Vacation Day Bag

My vacation day bag includes:

1. my sketchbook
2. camera
3. iPad Mini
4. stylus
5. books (Die Empty and Daily Habits)
6. travel sized watercolors and water brush
7. pens
8. colored pencils
9. iPhone
10. my brain

Will see how many of these items I actually use during this trip and report back. What art supplies do others bring when they travel? 

Thinking about my home of Boston today while on vacation at Disney with my family. Good luck to all those running in the Boston Marathon today.
