It can be brutally hot out in the field during these summer months. To cool yourself off quick, take a wet knap (the ones you get from restaurants) open it up. Take it out. Now turn on the A/C in your squad car and set it on full blast. Hold the wet knap up to the A/C vent for just a minute. Now take it and place it on the back of your neck, or place it on your face.
Instant cool will follow. ENJOY!
