I walk to whole foods, or sometimes I take citi bike to hmart, or I take the train to citarella

Generally backpack, yes. I have a big ass chrome bag if I'm shopping in anger, but my cute liddle jansport bag does the trick for daily trips. Used to use my ortliebs when I had a steel clunker but I got rid of it because after I upgraded to a crabon bike I just started using citi bike for the clunker trips
