Hiker beware. I was robbed at 3:00pm in the afternoon at one of the most crowded parks in the city. I won't go on and on about my tragedy, just know the police told me 3-4 cars are broken into here every week. I'm so disappointed the park doesn't tell you there are thieves on the park grounds watching the behaviors of hikers with the intention of breaking into their cars. The cash, credit cards, emptying my bank account in the span of an hour is hideous, but taking irreplaceable personal items is heartbreaking.
Don't trust the park to watch your car or fellow hikers.
