I have been reading your articles on parking at the trail head for South Mountain Park. My wife and I just moved to Phoenix from Minnesota. Minnesota parks have a real simple program: Pay $20, get an annual sticker for your car windshield, and you are set to park at any site for a year. I think this would be a much easier system for everyone. We hike the Telegraph and Desert Classic trails multiple times a week and would gladly pay a $20 annual fee to help support the parks and city.
