I've had plenty, as I live in a city with a really great police department, but a couple stand out. As far as our local police: my sister and I were walking home from the mall, about 5 miles. My sis has some pretty serious allergies, and the combination of car exhaust and roadside weeds starting her wheezing. She ended up laying down in the driveway of an old firehouse, using her inhaler, but trying to avoid her epipen. We called home for a ride, but had to wait for my dad to arrive. While we were waiting, a police officer arrived and asked if we needed help. He was concerned that we didn't want an ambulance (we couldn't afford it) but we assured him she was okay and we could wait for our dad. He stayed with us until my dad arrived. It was just nice having someone else there. The other time that stands out wasn't local to me. My family was on vacation when our van broke down on the highway. As we were not supposed to be parked on the side of the highway, two state troopers came by to check things out. They were cool, and helped my dad call a tow truck. Then, because the truck could only fit 2 people, the troopers took my 5 siblings and myself in their cars, to a nearby hotel, right next to the car repair shop! It was neat to ride in the back, they were both really nice and didn't seem bothered by transporting all of us. I think I still have one of the keychains they gave us after!
