I have to take transit almost everywhere, too.
I still do it. I walk to the grocery store and take the bus home (even though I get PTSD at the bus stop, where I was attacked once). I don't have mobility issues, but I am getting older, and I am technically a senior now!
Seattle has made it nearly impossible to shop using transit and downtown is essentially gone, but my larger point is, how did this happen? I used to have a good bus that took me within a block of three different grocery stores. Now one of the stores is gone (ironically replaced by a light rail stop), one is Whole Foods which I now boycott because it's Amazon, and the third one I can no longer get to from downtown on one bus. A 29-minute trip on one bus turned into a 55-minute trip on two buses and Metro defends it and actually argued with me online about the time difference.
I don't understand why consumers knowingly made shopping in person more difficult. It was easy. Now it's hard. Why?
