in all the stories like these I've seen so far are 2-bus trips.
Health reasons keep me from long trip times (more than say 3 hours), lack of time (piles of papers on floor need attending to and a long must-do list, admittedly if I seriously cut back on DU time, I'd make better progress on that),
finally, I rarely eat out (and never order prepared food) because of the extraordinarily high sodium and fat content.
But I do think of finding an immigrant restaurant within one-bus range for the rare times that I do eat out (a couple times a month).
To eat, it's pretty much all groceries that I walk about 55 minutes to Cub Foods for exercise, take the bus rest of way, then home on the bus with groceries (though still have a very exercise-worthy walk with a backpack full of groceries + 4 heavy bags of about 30 minutes) from the bus stop to home.
One bright spot is that as a senior, my bus fare is $1, and that covers the return trip too, because I do the "to" trip and the "from" trip within the 2.5 hour free transfer window.
