You didn't ask how to go hiking in the mountains, you asked how to "leave city limits". but you could still bike, go with friends, or rent a car for a day if no buses go where you want. Hiking locations tend to have lots of tourists so there would likely be bus routes, however.
Sure, that's true - though I can see a couple dozen of them out of the window behind my desk, and there'd be lots more if I were on the other side of the building - but I was really just replying to the previous commenter's mockery of the idea that one could go to the mountains via bus. It's not only possible, it's routine!
Bullshit, I'm from the Puget Sound and it hardly covers any of the good trails in the Cascades, nor could it do so practically if service were ever expanded.
Yeah, and when my grandpa was a kid, instead of a 20 minute drive to the neighboring town, it literally took them three days on foot because of all the hills, sloughs, and rivers. Cars and their associated infrastructure are a modern miracle, and the luddites opposed them are extremely foolish.
Are you claiming that an occasional need for a car dictates that every person needs their own dedicated full time car and that all dwellings need associated parking?
