My Running Baggage

I used to head out for a run with nothing but myself.  Once music became more portable, that was mandatory to bring along.  Then came a house key.  A cell phone.  A whistle (post dog-bite).  Thanks to Pilates and Yoga I became able to run farther.  More miles = a longer time running so I had to start bringing water with me.  A few spooky stories of runners and dangerous situations and I finally decided it was time for pepper spray.  JF ordered a hand-held bottle for me.
Wow.
There are days when I head out for a run and I feel like I am packing for a cross-country hike.  A big difference from the days when it was just me and my hands were free.  I now feel unbalanced when I don't have something in each hand.  So crazy.
My baggage:
Handheld water bottle held that I wear on my wrist.
iPhone held in one hand.  The arm bands are always too big.  Plus I sometimes change songs based on my mood, so, yeah...
House key around my wrist.
The new addition, pepper spray in the other hand.

The first few blocks felt strange as I was getting used to my new add-ons, but by the time I hit the first half-mile I felt just fine.

What do you take out on a run with you?  How has it changed over the years?
