For example, I went to visit the beach, which is on a national park. Parking required an app. There were park rangers there, the location was staffed, but they did not accept cash or credit card. Just an app. And there are two phone operating systems now, Apple and Android. So no. Can’t live without FAANG. I ended up downloading the app on the spot and purchasing a pass.
I’m sure the park service does this for their convenience. And it’s so populated near the coasts that if anyone doesn’t comply, they still have plenty of people who would gladly use the app. They can get away with demanding smartphone use. You can certainly get away with not having a smartphone further inland, and not needing to depend on FAANG explicitly. But I know this expectation is going to creep into the continent over time. In 5 years, if you say “I don’t have a smart phone” you’ll just be denied service. Period. No questions asked. And you will be considered the unreasonable party by most.
