The Boulder Emergency Squad was there showing off the Jaws of Life. Right when I walked up, they popped out both windshield into pieces and had the 'victim' out in a matter of minutes.
Code 3 Associates impressed me most of all that day, though all these heroes palpably inspire me. I've never heard of Code 3 before, a disaster response team for animal rescue. They're equipped with a huge rig to house the team and treat the injured animals. They travel to disaster nationwide and don't charge for their services.
On top of all the inspiration, the day was just a lot of fun.
