Not sure why you are being downvoted into oblivion. What you are saying is very true, but where we disagree is that roads are the only solution. Last night, I was looking at a short trip l need to make this weekend (here in the US): 14 min by car, 58 min by rail (with a 20 min walk to get to the station), 1h20 by bus. We brought that on ourselves, we’ve made it so that cars are the only viable option - but better public transit for example would make things a lot better, for a lot of people.

Yes, on the Thank God Ledge, on Half Dome.

So much this. Just subscribed, I hadn’t realized.
