Emergency Number 911 & Urban Rental-Car Rule #1
Across all 50 states and Washington, D.C., dial 911 (free from any phone) for Police, Fire, or Ambulance emergencies. In major coastal cities—especially San Francisco, Oakland, Los Angeles, and Seattle—never leave a single bag, jacket, or charging cable visible inside a parked car, even for 10 minutes at a scenic overlook. Store all luggage flat inside a locked trunk BEFORE arriving at your parking spot, or drop bags at your hotel bell desk first.
National Park Hazards: Desert Heat, Flash Floods & Wildlife Distances
In Southwest parks (Grand Canyon, Zion, Death Valley, Arches) from May through September, carry at least 1 gallon (4 liters) of water per person per day plus salty snacks, and avoid hiking in direct sun between 10:00 AM and 4:00 PM. In Yellowstone and Grand Teton, federal law requires staying at least 100 yards (91 m) from bears and wolves, and at least 25 yards (23 m) from bison, elk, and all other wildlife.
